Question

Cross a roan bull and a roan cow. What phenotypic and genotypic ratios would you get?

Answer 1

You would get 25% red (RR), 50% Roan (RW), and 25% white (WW)

Answer 2

The answer is: 100%.

Step-by-step explanation:

According to Mendel's laws, and taking into account that bulls and roan cows have red and white hairs together.

We will use "F" for the animal hair color allele.

F R = allele for red hairs

F W = allele for white hairs

red x white -------> red and white animals

F R F R x F W F W ----> 100% F R F W

The answer is: 100%.
