Polled Shorthorns

Genetic crosses question?

Can you show me the parents and gametes like how you work it out..thanks
In shorthorn cattle,the colours red and white show incomplete dominance,In addition,the polled condition(without horns)is dominant over the horned condition.Show the results of a cross between a horned roan male and a polled white female?

For color, R=red and W= white; for polled, H=no horns and h=horned. So the cross is:

RWhh x WWH_

The “_” is because we don’t know if the female is heterozygous or homozygous for Horned.

The male produces Rh and Wh gametes; The female produces WH (and maybe Wh, if she’s heterozygous).
