In squash plants, the allele for yellow fruit (y) is dominant to the allele for green fruit (y). a plant with genotype yy is crossed with a plant with genotype yy.

what are the expected genotype percentages in the offspring of this cross?

question options:

a)

100% heterozygous and 0% homozygous

b)

50% homozygous dominant and 50% heterozygous

c)

50% homozygous dominant and 50% homozygous recessive

d)

25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive

Y - yellow

y - green fruit

P:             YY                    x                  Yy

G:                    Y               x               Y        y

F1: YY, Yy

F=1

G=1:1

All offspring are a yellow

                   Y                  y

Y                YY                  Yy

the right answer is B)   50% homozygous dominant and 50% heterozygous.

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.
