Epistasis Bulb color in onions is determined by two genes that show epistasis. Pigment is only produced when the N allele is present. Individuals of the n genotype have no color (white). If color is present, it may be determined by the P or p alleles at the second gene. PP or Pp results in purple color, while pp results in yellow bulbs. 1 What F, and F2 genotypic & phenotypic ratios are observed from a cross between PPNN and ppnn onions? a F genotype: ;F, phenotype: b F2: C F2 phenotypic ratio:

. The production of pigment in the outer layer of seedsof corn requires each of the three independently assorting genes A, C, and R to be represented by at leastone dominant allele, as specified in Problem 64.

1. In a plant species, flower-colour is determined by the biochemical pathway shown below: E В C Colourless orange pink purple green Genes A, B, C, D, and E are independently assorting. The dominant alleles A, B, C and D encode enzymes that catalyse the corresponding reactions indicated above. The recessive alleles a, b, c and d are non- functional and do not produce active enzymes. The dominant E allele totally inhibits the action of gene D, while the recessive allele e has no effect. a) Determine the F1 and F2 phenotypes from a cross between AABBccDDEE and AABBCCDDee plants.

5) Scale color in dragons is determined by two genes. The W gene is epistatic to the G gene. The W allele is dominant and allows the production of pigment, while w is recessive and blocks pigment formation, resulting in white dragons. When pigment formation is possible, the dominant Gallele results in green dragon scales, while the recessive g allele results in black dragon scales. The pigment formation pathway is shown below. W (Enzyme 1) G (Enzyme 2) White precursor Black intermediate pigment → Green pigment a. What color scales would you expect in each of the following dragons? WwGg Wwgg wwGG wwgg b. If you cross two dragons with WwGg genotype, what is the expected phenotypic ratios of the progeny? c. What kind of epistasis do we observe?
