Question

When heterozygous advantage exists, how would you describe the fitness of the heterozygous genotype?

Answer 1

When heterozygous advantage exists, the fitness of the heterozygous genotype has higher fitness than either homozygote.

What are genotypes and phenotypes ?

A person's genotype is made up of all the alleles they have for a certain gene. The sum of a person's attributes or observable characteristics is their phenotype. The phenotype of an organism is only impacted by its genotype, which is directly inherited from its parents.

Types of genotype :

There are three different genotype types: homozygous dominant (PP), homozygous recessive (PP), and heterozygous (Pp). The traits are the same in homozygous dominant and heterozygous genotypes.

Heterozygous

The existence of two unique alleles at a specific gene locus. One normal allele, one mutant allele, or two separate mutant alleles may be present in a heterozygous genotype.

Homozygous

Contrary to a heterozygous genotype, a homozygous genotype exists. You inherited two copies of the same allele if you have a gene called homozygosity. In other words, both of your biological parents contributed the same variations.
