a. A variety of fruit bearing plants with the dominant allele A produces cream-coloured fruit while aa plants produce pink or red fruit. Red fruit is produced if allele B is present, and pink fruit is produced when the genotype is bb. What are the expected F2 phenotypes and proportions from intercrossing the F1 offspring of a cross between two plants with the genotype AAbb and aaBB? b. A certain animal can have brown, red, black or gray fur. Assume that fur colour is controlled by a single gene with multiple alleles in a dominance series where black (B1) > brown (B2) > red (B3) > gray (B4). Give the genotypes of two phenotypically different heterozygotes that when crossed produce offspring with the phenotypic ratio of 1 red : 2 black : 1 brown.

A wound is damaged or breaks in the surface of the skin. The wound is divided into two types, they are acute wound that includes minor cuts, laceration, bites, etc, and chronic wounds that can become slow to heal including ulcers on the legs and feet. R…
