In cattle, the hornlessness gene dominates the horniness gene, and the black coat gene dominates

In cattle, the hornlessness gene dominates the horniness gene, and the black coat gene dominates over the red gene. Both pairs of genes are on different pairs of chromosomes. What will be the calves, if you cross heterozygous for both pairs of signs of a bull and a cow.

Let the gene for the hornlessness of cattle be B, then the gene for the development of horns is b.

Let the gene for the black wool of cows be C, then the gene for the red suit is c.

Let us write down the genotype of heterozygous for both designated traits of a bull and a cow – BbCc. Such individuals will produce sex cells BC, bc, bC and Bc.

The offspring from crossing such a cow and a bull will look like this:

black hornless calves (2ВbСС, ВВСС, 2ВВСс, 4ВbСс);

black horned calves (2bbСс, bbСС);

red horned calves (bbcc);

red hornless calves (2Bbcc, BBss).
