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>
