Mice have two forms of the gene for hair texture. Straight hair (H) is dominant to curly hair(h). They also have two forms of the gene that determines the length of their tails. Short tails(T) are dominant to long tails(t). What would be the phenotypic ratio of the offspring if a mouse that was heterozygous for straight hair and had a long tail was crossed with a mouse that had curly hair and was heterozygous for tail length.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

a. to encourage apoptosis
