Understanding Heterozygosity: What It Means and Its Importance in Genetics

Heterozygous refers to an individual having two different alleles (forms) of a particular gene. This means that the individual has one copy of the gene from each parent, and the two copies are different.
For example, if a person has the genotype Aa for the ABO blood type gene, they are heterozygous for that gene because they have one A allele and one a allele.
Heterozygosity is the state of having two different alleles of a gene. It is important in genetics because it can affect the expression of traits and the probability of inheriting certain characteristics from parents.
