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. A certain variety of plant may have green seeds or brown seeds. The seeds may be full or shrunken. The following reciprocal crosses are made. ( picture) Explain the inheritance mechanisms that produce these results and where applicable indicate the dominance relationship. b. A species of bird may have feathered or naked feet. A female bird homozygous for feathered feet is crossed with a male bird homozygous for naked feet. All the male offspring have feathered feet and all the female offspring have naked feet. When the F1 offspring are crossed with each other, the resulting F2 are produced in the following ratios: Males: 3 feathered : 1 naked Females: 3 naked : 1 feathered Explain the inheritance mechanism that produces these results and indicate the dominance relationship.
a. A certain species of beetle may have a smooth or rough plate over the thorax. The plate may be translucent or opaque.
