Question 7
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 dominant guinea pig is crossed with a female heterozygous 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
