Question

If one parent is heterozygous white (Ww) and the other is homozygous black (ww), give the phenotype and genotype ratios for this cross.

Answer 1

Answer:           Phenotypic ratio is 1:1. Genotypic ratio is 1:1 as well

Explanation:

p1:                           Ww  x   ww

gametes:                       w,W      w,w

                                     .......cross......

F1:                             Ww (2) and ww (2)

                                (white)         (black)

therefore,

gen. ratio- 1:1

phen. ratio- 1:1

Answer 2

Answer:

Phenotype:

1/2 white 1/2 black

Genotype ratio Ww:ww

1:1
