In guinea pigs the allele for a rough coat r is dominant for the allele for a smooth coat r a heterozygous guinea pig and a homozygous recessive guinea pig are mated lists the distribution of geno?

When a heterozygous guinea pig (Rr) is mated with a homozygous recessive guinea pig (rr), the possible genotypes of their offspring are 50% Rr (heterozygous, rough coat) and 50% rr (homozygous recessive, smooth coat). This results in a genotype distribution of 1:1, with half of the offspring expected to have rough coats and the other half having smooth coats.
