Question

Color in squash is controlled by epistatic interactions in which color is recessive to no color. At the first locus white squash (W) is dominant to colored squash (w). At the second locus yellow (Y) is dominant to green (y). What is the phenotype of a squash with the genotype wwYy?

a) white
b) green with yellow strips
c) green
d) yellow
e) white with yellow strips

Answer 1

Answer: yellow

Step-by-step explanation:

Phenotype refers to the observable physical properties of an organism. phenotype is determined by its genotype. Phenotype is a description of your ones physical characteristics.

From the question, the first locus which is a white squash (W) is dominant to colored squash (w) and the second locus yellow (Y) is dominant to green (y).

ww(that is; the coloured squash) are not dominant while y (that is the green) is also not dominant but only the Y(that is ; the YELLOW squash) is DOMINANT.

Therefore, the phenotype of the squash will be Yellow.
