#Question id: 11626


A locus determines the type of pigment produced in the squash, with yellow (Y_) dominant over green (yy). This locus is expressed only in ww plants, which lack the dominant inhibitory allele W. We can assign the genotype ww Y_ to plants that produce yellow squash and the genotype ww yy to plants that produce green squash. The genotypes and their associated phenotypes are:


What will be the correct prediction about these pathway?

  1. Allele w is epistatic to Y and y
  2. Allele y is epistatic to W and w
  3. Allele W is epistatic to Y and y
  4. Allele Y is epistatic to W and w
