Essay

Below is a simplified version of the biochemical pathway responsible for fruit color in peppers.Suppose that gene A encodes enzyme 1,gene B encodes enzyme 2,gene C encodes enzyme 3,and that each gene only has two alleles: completely functioning (capital letters)and null (lower case letters).Note that red plus chlorophyll is brown,but yellow plus chlorophyll is green.

a)A breeder crossed two pure lines of peppers and then selfed the resulting F₁.The F₂ was comprised of 351 plants with red peppers,115 with yellow peppers and 154 with colorless (white)peppers.What must have been the genotypes and phenotypes of the two original pure lines?

b)A pure-breeding plant with green fruits is crossed to a pure-breeding plant that makes yellow fruits.All the F₁ plants make yellow fruits.The F₁ is selfed,and in F₂ we have 250 plants with yellow peppers,84 with colorless peppers,and 112 with green peppers.What must have been the genotypes and phenotypes of the original pure lines?
