If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.
Allele for short hair (S) is dominant on the allele for the long hair (s).
The texture of hair texture is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).
Now coming towards the question:
- A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.
Phenotype of the female will be Rough and long hair.
- A male guinea pig is homozygous dominant for hair texture and hair length.
Phenotype of the male will be Rough and short hair.
Hope it help!
