Question 26
The Ultimate Guide to Guinea Pig Breeds, Markings and Colors – Kavee USA

In guinea pigs, rough coats (with lots of swirly cowlicks) are dominant over smooth coats. If a male homozygous recessive guinea pig is crossed with a female homozygous dominant guinea pig, what are the possible genotypes and phenotypes of the offspring? Complete the Punnett square and the percentages of rough and smooth coated offspring.

***Please follow all Punnett square rules to complete this question. (Letters and numbers, only)

Please use the following: Rough = R and Smooth = r




offspring 1 offspring 2
offspring 3 offspring 4

% rough

% smooth

Answer 1

Offspring 1: Genotype: Rr, Phenotype: Rough
Offspring 2: Genotype: Rr, Phenotype: Rough
Offspring 3: Genotype: Rr, Phenotype: Rough
Offspring 4: Genotype: Rr, Phenotype: Rough

% rough: 100%
% smooth: 0%
