In cats, short hair dominates over long. A heterozygous shorthair cat interbred with the same cat

In cats, short hair dominates over long. A heterozygous shorthair cat interbred with the same cat and gave birth to 8 kittens. How many kittens were genotypically similar to their parents?

Let’s designate the gene that causes the development of short hair in cats as K, then the gene that causes long cats in the homozygous variant will be k.

Heterozygous, according to the condition of the problem, the cat and the cat will be Kk. They will produce K and k eggs and sperm.

The possible offspring from the data of the cat and the cat will look like this:

short-haired kittens (KK and Kk) – 75%;

kittens with long hair (kk) – 25%.

Find the number of shorthaired kittens: 8 * 0.75 = 6.

Answer: 6 kittens will look like their parents.
