WebIn drosophila, a recessive mutation (m-) of a maternal effect gene results in an abnormal phenotype wherein homozygous (m-m-) females produce eggs that cannot support embryonic development. Homozygous (m-m-) males, however, can still produce viable sperm. Using m+ to denote a normal gene, determine the genotypes and phenotypes of … WebFor a trihybrid cross, the F 2 phenotypic ratio is 27:9:9:9:3:3:3:1. The forked-line method can be used to analyze a trihybrid cross. Here, the probability for color in the F 2 generation occupies the top row (3 yellow:1 green).
