Shorthorn cattle may be red, white, or roan in color. the roan is an intermediate coloration due to a mixture of red and white hairs, and is the result of incomplete dominance. a breeder of shorthorn cattle has cows which are white, and a bull which is roan. what proportion of the calves produced in this herd will be white?

Half or 0.5

Explanation:

Let the alleles for the cattle color be R and r. So,

RR = Red

Rr = Roan (incomplete dominance)

rr = white

When the breeder mates white cow (rr) with roan bull (Rr) :

      R      r

r     Rr     rr

r     Rr     rr

Half or 0.5 of the progeny has rr genotype so 0.5 of the progeny will be white in color.

would be most reasonable answer tbh
