Color blindness is a recessive X-linked trait. A normal couple has a color-blind child. At least one member of the couple's families is colorblind, who is this most likely to be?a) the child's paternal grandmotherb) the child's paternal grandmother or grandfatherc) the child's maternal grandmotherd) the child's paternal grandfathere) the child's maternal grandfather
Answers
Answer:
c or e
Explanation:
The correct answer would be the child's maternal grandmother or grandfather.
For X-linked traits, only females can be carriers while males are either affected or totally free from the trait. This is because females have two X (XX) chromosomes while males have only one (XY).
Since the couple is normal, it means the father is free from color blindness. The only available option now is the mother and since she is phenotypically normal, it means that she is a carrier of the disease. She must have inherited the allele from either of her parents, but not from both. If she had inherited an affected X chromosome from each of her parents, she would have been phenotypically affected for color blindness.
Hence, the child's color-blind allele can only be traced back to either of the child's maternal grandmother or grandfather.
The correct option is c or e.
The member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.
An X-linked recessive inherited genetic trait is transmitted from parent to child through mutations in genes localized on the X chromosome.In males, X-linked recessive traits are always expressed because males contain only one X chromosome.In consequence, in this case, the mother should be a normal carrier of the disease/condition, thereby her dominant X-linked allele can mask the expression of the recessive (daltonic) allele, which is passed to the child from the maternal grandfather.In conclusion, the member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

Answers
Answer:
The correct option is a) the relative distance between the genes.
Explanation:
A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close have a few recombination events and are strongly bounded. These genes are linked.
The percentage of recombination frequency (P = Recombinant number / Total of individuals) is useful to determine the genetic distance between two or more genes. This distance results from multiplying that frequency by 100 and expressing it in map units (MU) or centiMorgans (cM). One centiMorgan (cM) equals one map unit (MU).
The map unit or centiMorgan is the distance between the pair of genes for which every 100 meiotic products only one results in a recombinant product.

list five different system interactions for the topic of acid rain
Answers
Answer:
1. Effects of Acid Rain on Fish and Wildlife
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
2. Effects of Acid Rain on Plants and Trees
Dead or dying trees are a common sight in areas affected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.
3. Buffering Capacity
Many forests, streams, and lakes that experience acid rain don’t suffer effects because the soil in those areas can buffer the acid rain by neutralizing the acidity in the rainwater flowing through it. The soil becomes thin because of this and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.
4. Episodic Acidification
Melting snow and heavy rain downpours can result in what is known as episodic acidification. This can result in short-term stress on the ecosystem where a variety of organisms or species may be injured or killed.
5. Nitrogen Pollution
It’s not just the acidity of acid rain that can cause problems. Acid rain also contains nitrogen, and this can have an impact on some ecosystems. For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.
Explanation:
Not sure if this is what the question was asking for.
Acid rain is defined as rain or any other kind of precipitation that is particularly acidic, including high quantities of hydrogen ions. Acid rain has a pH lower than drinking water, ranging from 4-5 on average.
What are the different system interactions for acid rain ?1. Acid Rain's Impact on Fish and Wildlife
Acid rain's biological consequences are most visible in aquatic areas such as streams, lakes, and marshes, where it can affect fish and other species. Acidic rain water can drain aluminum from soil clay particles as it passes through the soil and into streams and lakes.
2. Acid Rain's Effects on Plants and Trees
In acid rain-affected locations, dead or dying trees are prevalent. Aluminum is leached from the soil by acid rain. Aluminum may be damaging to both plants and animals. Acid rain also depletes the soil of minerals and nutrients required by trees to develop.
3. Capacity for Buffering
Many woods, streams, and lakes that experience acid rain remain unaffected because the soil in such locations can buffer the acidity in the precipitation flowing through it. As a result, the soil becomes thin and unable to effectively neutralize the acid in the rain water. As a result, these locations are more sensitive, and the acid and aluminum can build up in the soil, streams, and lakes.
4. Acidification on Occasional Basis
Melting snow and strong rain can cause a condition known as episodic acidification. This can cause short-term stress in the environment, injuring or killing a range of creatures or species.
5. Nitrogen Pollution
Not only may the acidity of acid rain cause difficulties. Acid rain includes nitrogen, which can have an influence on some ecosystems. Nitrogen contamination in our coastal waterways, for example, is partly to blame for dwindling fish and shellfish populations in some locations. Aside from agriculture and sewerage, much of the nitrogen created by human activities that reaches coastal waterways originates in the atmosphere.

Explanation:
Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?
Answers
Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable
Answers
Answer:
temperature
Explanation:
The independent variable would be the colored water at different temperatures.
The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.
In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.
