Question

In guinea pigs, the allele for rough fur (R) is dominant over the allele for smooth fur (r). A male guinea pig with smooth fur and a female guinea pig with rough fur have an offspring that has rough fur. What are the possible genotypes for the fur type of the female guinea pig and her offspring

Answer 1

Answer: Female could have either Rr or RR, her rough fur offspring MUST have Rr

Step-by-step explanation:
the offspring inherited a (r) from the male and a (R) from the female

Male: rr
Female: either Rr or RR
offspring must have Rr
