The offspring which carries the allele II will be homozygous dominant.

Explanation:

A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.

A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.

Hence, a homozygous dominant trait will carry the alleles II.
