Two homozygous recessive flies are crossed
WebA genotypically wild-type fruit fly is crossed to a fly with homozygous recessive mutations in two different genes that result in a wingless and an eyeless phenotype. The F1 generation is 100% phenotypically wild type. Two of the phenotypically wild-type F1 flies are mated and the following offspring are observed in the F2 generation: Wild type ... WebSelf-pollination of the F{1} generation results in an F_{2} generation with a 3 to 1 ratio of yellow to green peas. One out of three of the yellow pea plants has a dominant genotype of YY, and 2 out of 3 has the heterozygous genotype Yy. The homozygous recessive plant …
