Black color in cats dominates over fawn, and short coat over long. Purebred Persian cats

Black color in cats dominates over fawn, and short coat over long. Purebred Persian cats (black long-haired) were crossed with Siamese (fawn short-haired). The resulting hybrids interbred with each other. What is the probability (in%) of getting a purebred Siamese kitten in F2? What is the probability of getting a kitten phenotypically similar to Persian in F2? What is the probability of getting a long-haired fawn kitten in F2?

Let’s solve a genetic problem.

Given:

O- black color.

o-pale color.

S – short coat.

s- long hair.

♂OOss – Persian cat.

♀ooSS is a Siamese cat.

Decision:

R: ♂OOss x ♀ooSS.

Gametes: Os, oS.

F1: OoSs.

R: ♂OoSs x ♀OoSs.

Gametes: OS, Os, oS, os.

F2: OOSS, OOSs, OoSS, OoSs, OOSs, OOss, OoSs, Ooss, OoSS, OoSs, ooSS, ooSS, OoSs, Ooss, ooSs, ooss.

Answer: The probability of getting a pure Siamese kitten is 6.25%

Phenotypic Persian – 18.75%

Long-haired fawn kitten – 6.25%
