As observed in labrador retriever coat colors in recessive epistasis, b locus regulates pigment production while e locus regulates pigment deposition to hair shaft. which gene is hypostatic?

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

i think that d. wind is the answer.   i missed the question when i answered a. currents.
