Question

A female cat has two recessive genes for long fur (ss) and a male cat has two dominant genes for short fur (SS). What is the likelihood the two cats produce a kitten with short fur?
A) 25%
B) 50%
C) 75%
D) 100%

Answer 1

The answer is D 100%

Answer 2

Answer:

Option D is correct

Explanation:

Given,

Genotype of female cat - ss

Genotype of male cat - SS

S represents the allele for short fur while s represents the allele for long fur.

Also S is dominant over s

The cross between SS and ss is represented by a punnet square as given below-

S S

s Ss Ss

s Ss Ss

Thus, all the offspring have a heterozygous genotype "Ss"

Therefor all the offspring will have short fur

Likelihood the two cats produce a kitten with short fur-

$\frac{4}{4} * 100$

$= 100$%

Option D is correct
