Question

1.     In summer squash, white fruit color is dominant, yellow is recessive. If a squash plant that is homozygous white is crossed with homozygous yellow, what will be the: a.     Genotype of the offspring b.     Phenotype of the offspring c.     Genotypic ratio d.     Phenotypic ratio

Answer 1

Here, Cross: = WW   ×        ww

Here, W(white) is dominant over w(yellow).

Offspring:  Ww , Ww, Ww, Ww

1) Genotypes: Ww , Ww, Ww, Ww

2) Phenotypes: They all will be "White"

3) Genotypic ratio = WW:Ww:ww = 0 : 1 : 0

4) Phenotypic ratio = White : Yellow = 1 : 0

Hope this helps!

Answer 2

C because the punnit square is just a possibility and you're trying to look for the genes
