In guinea pigs, rough coats (with lots of swirly cowlicks) are dominant over smooth coats. If an RR guinea pig is crossed with a Rr guinea pig, what are the possible genotypes and phenotypes of the offspring? What are the chances of each?

Verified answer
The genotypes of the offspring will be RR and Rr in the ratio of 1:1.
The phenotypes of the offspring will be all rough coats.
Explanation:
Genotypes refer to the allelic constituents of the genetic build-up in an organism. Phenotypes refer to the visible characters morphologically of an organism.
The cross is provided in the picture.
Results - 2 RR genotypes and 2 Rr genotypes are seen.
Thus, the genotypes are RR and Rr with a ratio of 1:1.
Since R is for rough coats, the phenotypes of all the offspring are rough coats.
