In roan cattle, red (R) and white (W) are codominant. Heterozygous individuals produce both red and white hairs, known as roan. When two roan cattle are crossed, what are the phenotypic ratios of the offspring

Answers

Answer 1

Answer:

1:2:1

Explanation:

To get the phenotypic ratios, first you must figure out the genotype results of the cross. If the two cattle both have RW, then you get 25% RR, 50% RW, and 25% WW.

This means you have 1 fully red cattle, 2 roan cattle, and 1 fully white cattle, or just simplified as 1 (red) : 2 (roan) : 1 white.

Answer 2

The ratio of red to white is 1:1, and the ratio of roan to non-roan is 2:1, which gives the phenotypic ratio of 1:2:1 for red:roan:white.

What is co-dominance ?

Codominance is a type of genetic inheritance in which both alleles of a gene are expressed equally in the phenotype of a heterozygous individual. This means that neither allele is dominant or recessive, and both contribute to the observable traits of the organism

When two roan cattle (Rr x Rr) are crossed, the possible genotypes of their offspring are RR, Rr, and rr. The phenotypic ratios of the offspring will be:

25% red (RR)

50% roan (Rr)

25% white (rr)

This is because both red and white alleles are codominant, meaning they are expressed equally in the heterozygous state (Rr) and produce the roan phenotype. The ratio of red to white is 1:1, and the ratio of roan to non-roan is 2:1, which gives the phenotypic ratio of 1:2:1 for red:roan:white.

Sources of energy and the two processes for land autotrophs (producers) and autotrophs in the deep ocean.

Answers

Autotrophs on land get their energy indirectly from the sun while those in the deep ocean get theirs from chemicals.

Photosynthesis and Chemosynthesis

Autotrophs on land get their energy from carbohydrates synthesized via photosynthesis.

Photosynthesis is a process that converts radiant energy from the sun to chemical energy locked in carbohydrates. These carbohydrates are then broken down during respiration in order to release the locked energy.

Autotrophs in the deep ocean lack access to sunlight and thus, cannot utilize radiant energy from the sun. Instead, they make their carbohydrates by making use of energy from chemicals like hydrogen sulfide and methane in a process called chemosynthesis.
