In shorthorn cattle, a roan cow mated with a roan bull always produces red, white, and roan claves in the ration of one red: two roan: one white. (Roan is produced by an even mixture of red and white hairs). If a breeder of shorthorn cattle has cows which are white and a bull which is roan:What proportion of the claves produced in his herd will be white?What proportion of the calves produced in his herd will be roan?What proportion of the calves produced in his herd will be red?Starting with a roan bull and white cows, as explained above, could you eventually establish a true-breeder red herd? Explain.

According to the Q&A guidelines, we are supposed to answer only three sub-parts. Kindly repost the question with the remaining sub-parts. Given information A roan cow mated with a roan bull always produces red, white, and roan calves. The ratio obtained is one red: two roan: one white. The genotypes are: Red- RR White- WW Roan - RW The cross occurs between a white cow (WW) and a roan bull (RW). Punnett square of WW x RW Gametes R W W RW- roan WW- white 1. The proportion of the white calves The offspring are roan and white which are in the ratio of 1:1 The proportion will be the number of white calves/ roan and white offspring= 1/2 = 0.5= 50% 2. The proportion of the roan calves The proportion will be the number of roan calves/ roan and white offspring= 1/2 = 0.5= 50% 3. The proportion of the red calves From the cross, only roan and white offspring are obtained. There are no red calves, so the answer is zero.

Question

In shorthorn cattle, a roan cow mated with a roan bull always produces red, white, and roan claves in the ration of one red: two roan: one white. (Roan is produced by an even mixture of red and white hairs). If a breeder of shorthorn cattle has cows which are white and a bull which is roan:

What proportion of the claves produced in his herd will be white?
What proportion of the calves produced in his herd will be roan?
What proportion of the calves produced in his herd will be red?
Starting with a roan bull and white cows, as explained above, could you eventually establish a true-breeder red herd? Explain.
