Question

In Guinea, pigs, rough Coats( with lots of swirly cow licks) are dominant over smooth Coats. If an RR Guinea pig is crossed with an Rr Guinea pig. What are the possible genotypes types and phenotypes types of the offspring? what are the cahnces of each ? inlude genotypic and phenotypic ratios

​

Answer 1

Possible genotypes are RR and Rr, but the only possible phenotype is Rough coats because there will always be a dominant R allele present in the offspring.
Chances:
50% RR
50% RR

100% rough
0% smooth
