The genotype percentage is 100 % of Yy genotype as all the individuals from this cross are of genotype Yy.
Step-by-step explanation:
Data given:
Yellow squash Y = dominant
white squash y = recessive
cross between YY X yy
genotype percentage =?
the cross between two squash colors will be seen in the Punnet square.
YY X yy
y y
Y Yy Yy
Y Yy Yy
Genotype percentage will be on the assumption that each box of the punnet square represents 25 %. We can see that all the individuals formed from the cross of homozygous dominant and homozygous recessive will yield heterozygous individuals with dominant phenotype.
the genotype percent is 100% of Yy genotype.
