Average heterozygosity refers to the average percentage of loci that are heterozygous in a population. Average heterozygosity is measured by looking at changes in karyotypes. The human genome consists of approximately 3 billion base pairs.
Heterozygous is a term that describes the genotype and just means that there are two alleles of different types. If you're heterozygous, you're Mm. You can't be heterozygous dominant or heterozygous recessive because by definition if you're heterozygous you have one of each allele.You only specify dominant or recessive when it's homozygous. So, in short, it's neither, it's just plain heterozygous.f you're heterozygous, you're Mm. You can't be heterozygous dominant or heterozygous recessive because by definition if you're heterozygous you have one of each allele. You only specify dominant or recessive when it's homozygous.
