What part of the hybrids from crossing Aa x AA is homozygous for a recessive trait?

In this case, one parent is heterozygous and carries the Aa genotype, and the second is homozygous, with the AA genotype. The first forms gametes A and a, the second forms A and A. After the fusion of gametes, the following hybrids are obtained: AA, AA, aA, aA. All individuals of the 1st generation will have the dominant gene A. Part of the hybrids with the AA genotype, namely 50%, are homozygous for the dominant trait. The second part is heterozygous (aA). There will be no homozygous hybrids for a recessive trait from such a crossing.
