When white-coated cattle (W) are mated with red-coated cattle (R), the offspring are roan (WR), meaning their coats contain both white and red hairs. This is an example of codominance.
A farmer breeds two roan cattle with one another.
What is the chance that their offspring will be roan?
Using a punnett square, crossing two heterozygous individuals results in a 25% chance of a white-coated cattle, a 50% chance of a roan-coated cattle, and a 25% chance of a red-coated cattle.
