a male guinea pig is homozygous dominant for hair texture and hair length. A female guinea pig is heterozygous for hair texture
nekit [7.7K]

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!
