Answer:
25% red
50% roan
25% white
Explanation:
When RR (red) is crossed with WW (white), it results in roan color.
RR (red) x WW (white)
RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
<u>Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.</u>
