Question

3 multiple choice 20 points if a homozygous dominant parent (aa) mates with a homozygous recessive parent (aa), what percent of their offspring will show the dominant trait? 25% 50% 100% 75%

Explanation:

Step1: Determine possible gametes

Homozygous dominant (AA) parent can only produce A gametes. Homozygous recessive (aa) parent can only produce a gametes.

Step2: Create Punnett square

	A	A
a	Aa	Aa

All offspring have genotype Aa. Since A is dominant, all (100%) will show the dominant trait.

Answer:

100% (The option corresponding to 100%)
