If you cross two heterozygous Yy pea plants,what fraction of the offspring will be yellow?

Question

Quizplus · Accepted Answer

In this case, the Y represents the dominant yellow pea color allele and the y represents the recessive green allele. Heterozygous Yy pea plants mean that they have one dominant and one recessive allele for pea color. When two heterozygous Yy pea plants are crossed, the Punnett square predicts that 75% of the offspring will have a yellow pea color (YY, Yy) and 25% of the offspring will have a green pea color (yy). Therefore, the correct answer is B) 75%.
