Question

PLEASE HELP IF YOU KNOW ABT PUNNETT SQUARES!!! Mendel conducted a cross between purebred organisms. Use a punnett square to show a cross between a purebred pea plant with yellow seeds and a purebred pea plant with green seeds. What would be all of the possible genotypes of all the offspring?

A. 100% yy
B. 100% Yy
C. 50% Yy and 50% yy
D. 75% Yy and 25% yy​

Answer 1

B

Step-by-step explanation:

I assume the plants with the yellow seeds are dominate (YY) , while the ones with green seeds are recessive (yy) (Since it would need to be recessive to be a different color than the dominate). The genes will always be heterozygous then, since it combines the genes from both parents.
