Coat color in cattle is an example of incomplete dominance. When cattle with solid white coats (W) are mated to cattle with solid red coats (R), the offspring are roan (WR), meaning they have coats containing both white and red hairs. A farmer mates two roan cattle. What is the chance that their offspring will have solid white coats? *

Answer:

There is a 25% chance for solid white coats.

Explanation:

To check the chances of a solid white coat offspring being formed, lets make a punnet square.

The gametes of the parents will be W and R v/s W and R.

         W           R

W    WW        WR

R     WR         RR

A punnet square is a diagram which is made to test the outcomes of a cross.

As the following punnet square shows:

  • There is 25% chance for solid white coat offspring to be formed (WW).
  • There is a 50% chance for the offspring to be roan (WR).
  • There is a 25% chance for the offspring to have solid red coats (RR).
