Question

In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive yA plant with genotype Yy and a plant with YY are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint. Draw a Punnett square to help you determine the answer) OA. 0 OB. 3 Oc. 1 OD. 2​

Answer 1

Answer: The correct answer is - B) = 1

As per the information given in the question, yellow leaves (Y) is a dominant trait over red leaves (y) that is it will mask the expression of red leaves whenever the allele for yellow is present with the allele for red leaves.

The possible genotype for yellow leaves is YY and Yy whereas for red leaves is yy.

The genotype of parents is - Yy and Yy.

When they are crossed with each other, they will produce one plant with red leaves out of four offspring.

Refer punnett square.
