In general, the frequency of crossing over between two linked genes depends on what?
How far apart they are on the chromosome
The characteristics that the genes code for
Whether the genes are dominant or recessive
The phase of meiosis in which the crossing over occurs
Answer:
Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.
The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
[tex]\huge{\color{magenta}{\fcolorbox{magenta}{black}{\huge{\color{white}{\fcolorbox{aqua}{black}{✿ᴀɴsᴡᴇʀ✿}}}}}}[/tex]
If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.

In these analyses, why are segments of chromosomes (haplotypes) rather than individual strs used to identify genetic relationships?
The type of analysis is not specified here, but haplotypes are used to identify phylogenetic and phylogeographic relationships.
Whta are haplotypes?The haplotypes are linear sequences of nucleotides whose order can be used to determine evolutionary relationships.
The haplotypes are very useful in phylogeny and phylogeography to study the features of species.
The term haplotype is broader than genetic sequence because a haplotype is more informative (a priori).

https://brainly.com/question/9977325
The segments of chromosomes (Haplotypes) are used to identify genetic relationship because it carries almost all the information, properties, and characteristics of the individual genome.
What do you mean by Genetic relationship?Genetic relationships may be defined as the similarities in the sequence of the genome between the organisms of two or more species.
Haplotypes are used to identify the evolutionary relationships between the species. It also analyzes the various features that a species possess in its genome.

Which drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract?.
Answer:
Anticholinergic drugs are common ingredients in antidiarrheal medications because they significantly decrease intestinal motility and secretions.
Anticholinergics drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract.
What are anticholinergics?Anticholinergics are a type of medication which blocks the action of a neurotransmitter known acetylcholine. Acetylcholine transfers signals between cells that affect specific bodily functions. As anticholinergics can affect a variety of functions, including digestion, urination, salivation, they can help treat many conditions.
The medication blocks acetylcholine from causing involuntary muscle movements in the gastrointestinal tract, lungs, urinary tract, and other areas of the body.

Why does the moon have craters in it?
Answer:
Because the Earth has an atmosphere, the Moon has more craters than the Earth. While we sweep up a lot more things because of our higher gravity, the majority of it burns up on entrance and never reaches the earth. Earth also possesses liquid water. This is significant in two ways: first, most things that strike water do not create a crater, and second, water erodes previous craters.

Which of Earth's spheres should the student study the most? the geosphere the atmosphere the hydrosphere the biosphere.
A student wants to learn how plants and animals interact with one another in an ocean habitat thus he should learn about the biosphere as it helps in the determination of living organisms.
Organisms want water, and they take it in from assets including lakes, rivers, the sea, and aquifers. A deer that sips water from a circulate recycles that water with the aid of using exhaling and excreting waste. A fish takes in water from the sea and excretes water again out.
What plants and animals live in the ocean?Seaweeds, algae, snails, crabs, small fishes, mollusks, worms, clams, and crustaceans stay withinside the coastal area. The pelagic area includes an open ocean further from the land and includes floor seaweeds, fish, whales, and dolphins.
