B 100% of his sperm would carry BOTH of the alleles (Aa)100% of his sperm would carry BOTH of the alleles (Aa)
C 50% would carry a dominant (A) and 50% would carry a recessive (a)50% would carry a dominant (A) and 50% would carry a recessive (a)
D 50% would carry two dominant alleles (AA) and 50% would carry two recessive alleles (aa)

Answer 1

The correct answer is:

C) 50% would carry a dominant (A) and 50% would carry a recessive (a).

When a man is heterozygous (Aa) for a trait, his sperm cells will carry either the dominant allele (A) or the recessive allele (a). Thus, half of his sperm will carry the A allele and the other half will carry the a allele.
