What are heterozygous parents?

Heterozygous parents have two different alleles for a specific gene, one inherited from each parent. For example, if a gene has two variants, such as A and a, a heterozygous individual would have the genotype Aa. This genetic diversity can influence the traits of their offspring, leading to a variety of possible phenotypes. Heterozygosity is important for genetic variation and can contribute to the adaptability of a population.
