A heterozygous genotype consists of two different alleles for a specific gene. For example, if we consider a particular gene where one allele represents a dominant trait (let's say "A") and the other represents a recessive trait (let's say "a"), a heterozygous genotype would be represented as "Aa". This means one allele is dominant (A) and the other is recessive (a). In contrast, a homozygous genotype has two identical alleles, either "AA" (homozygous dominant) or "aa" (homozygous recessive).
Which genotype is heterozyous?
