In cows of the Shorthorn breed, the Red color dominates over the white state of the animals.

In cows of the Shorthorn breed, the Red color dominates over the white state of the animals. The paint of animal animals of the animal is created from the crossing of variegated cows with a red bull. What percentage will have a white paint.

Let’s designate the gene that determines the red coat color as C, the gene that causes the white coat of cows as c. Variegated cows will have a heterozygous Cc genotype.

The Cc variegated cows produce two types of eggs – C and c.

Bulls with red hair will be homozygous for the red color gene – CC. They will produce the same type of sperm C.

When crossing a red bull and a variegated cow, the offspring will be represented by the following options:

variegated calves (Cc) – 50%;

red calves (CC) – 50%.

Calves with white wool cannot be born from such parents.

Answer: 0%.
