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.
A heterozygote advantage (heterozygous advantage) describes the case in which the heterozygote genotype has a higher relative fitness than either the homozygote dominant or homozygote recessive genotype. common example is the case where the heterozygote conveys both advantages and disadvantages, while both homozygotes convey a disadvantage. A well-established case of heterozygote advantage is that of the gene involved in sickle cell anaemia.
