Heterozygous, as related to genetics, refers to having inherited various versions of a genomic marker from each organic parent. Therefore, an individual that is heterozygous for a genomic marker has two various versions of that marker. Heterozygous is a state of having acquired various forms of a particular genetics from each one of your organic parents. Words "heterozygous" merely suggests that your organic mother and your biological dad, when they contributed their duplicates of a certain gene to you, they did so in a manner to make sure that the DNA series is a little different. And in the situation of a homozygous genotype, we're discussing a situation where we've obtained identical forms of a specific genetics from each organic parent. That is, if we were to read along the DNA series that mommy gave you and the DNA series that dad offered you, we would discover definitely, positively no distinctions because gene or in the area of the gene that we're concerned about.
