If Y homozygous dominant then what is hetrozygous n homozygous recessebe?

If Y is homozygous dominant, it means it has two dominant alleles (YY). A heterozygous genotype would contain one dominant allele and one recessive allele (Yy), while a homozygous recessive genotype would have two recessive alleles (yy). Therefore, in this scenario, the heterozygous individual expresses the dominant trait, while the homozygous recessive individual expresses the recessive trait.
