a. You buy an ornamental flowering plant with red flowers. Red flowers are found when both a D and an E allele are present. Either a D or an E allele produces orange flowers and ddee plants have yellow flowers You cross your red-flowered plant with an orange-flowered plant. You obtain offspring in the following ratios: 3 red : 1 yellow : 4 orange. What are the genotypes of the red-flowered and orange-flowered parent plants? 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 gray : 2 brown : 1 red. (2) Please label your answers a and b.
