Can heterozygous be dominant
WebDec 29, 2024 · Heterozygous is the state in which an allele contains one dominant gene and one recessive gene. Heterozygous recessive is not possible as the recessive gene doesn’t express in the presence of a dominant gene.

Dominant Genotypes: There are two types of dominant genotypes when following the patterns of Mendelian Inheritance. One is the homozygous dominant genotype (AA), which has two copies of the dominant allele. The other is the heterozygous genotype.
