Concept

Problem: In cats, the hair can be either short or long (angora). A cat fancier made the following crosses with results shown below:a. Which phenotype is dominant?b. What are the genotypes of the parents and offspring of the crosses?c. If the short-haired offspring from cross 3 were bred to their short parent, what kinds of kittens would be expected and in what proportions?d. If the short-haired offspring from cross 3 were bred to the short-haired parent ofcross 2, what kinds of kittens would be expected and in what proportions?

FREE Expert Solution

The hair length of cats is known to assort independently from the other genes. In this trait, there are two possiblephenotypes: the short and long (angora). In the given crosses, it is the second cross that could give us a clue on which character is dominant and which is recessive.
