4. In guinea pigs, the genes for coat texture and coat colour are found on separate chromosomes. The allele for rough coat is dominant to the allele for smooth coat. The allele for black coat is dominant to the allele for white coat. A black guinea pig with a rough coat was crossed with a white guinea pig with a rough coat. The cross was repeated on a number of occasions and the phenotypes of the offspring were as follows: 28 rough and black coats 31 rough and white coats 11 smooth and black coats 10 smooth and white coats Complete the genetic diagram to explain this cross. Use the following symbols to represent the alleles: R = rough B = black Parental phenotypes: rough and black coat Parental genotypes: Gametes: Offspring genotypes: Offspring phenotypes: Expected phenotypic ratio:. r = smooth b = white X rough and white coat
