Drlmbrid 에 Ans 1.12.- yewes grem = (83) ane Colordoy rai 2- eu G

This cross is a case of dominant epistasis in which dominant W Gene affects expression of other gene G which is said to be hypostatic gene . The ratio is thus 12:3:1 . Unless W Gene is in homozygous recessive condition yellow fruit will not be produced .

Please provide details: White fruit color in summer squash is governed by a dominant gene (W) and colored fruit by its recessive allele (w). Yellow fruit is governed by an independently assorting hypostatic gene (Y) and green by its recessive allele (y).

Two independently assorting genes help determine fruit color in squash. At the first locus, the W allele codes for a dominant white phenotype, whereas the w allele allows colored squash. At the second locus, the allele Y codes for a dominant yellow phenotype, and the allele y codes for a recessive green phenotype. The interaction between these two genes is an example of dominant epistasis, with the W locus acting as the epistatic locus and the Y locus acting as...

You cross two crows, one with yellow legs, and the other with green legs. All of the F1 offspring have purple legs. Leg pigment is produced by the pathway in Fig.3, where the dominant alleles (Y and G) produce functional versions of enzymes Y and G, and the recessive alleles (y and g) produce nonfunctional enzymes. What genotype frequencies do you expect to see in the F2 generation? O all purple 9 green: 3 purple: 3 yellow 9 purple: 3...
