When heterozygous advantage exists, the fitness of the heterozygous genotype has higher fitness than either homozygote.
<h3>What are genotypes and phenotypes ?</h3>
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.
<h3>Types of genotype :</h3>
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.
<h3>
Heterozygous</h3>
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.
<h3>Homozygous </h3>
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.

Answer:
Meiosis
Explanation:
The process accounts for species diversity is Meiosis. Meiosis is termed as a specialized cell division which reduces chromosomes number by half and then creates for haploid cells.
Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication.
Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
The correct option is B.
The field of science is very dynamic and it thrives on discovery of new evidences. When new evidence are found for a particular phenomenon, the existing phenomenon has to be adjusted to fit the new discovery. Air pollution was once named to be responsible for global cooling because enough evidence was not available then to prove otherwise but now overwhelming evidences show that pollution is responsible for global warming.<span />
Answer:
Most nonrenewable resources are formed from organic carbon material which is heated and compressed over time, changing their form into crude oil or natural gas. The term nonrenewable resource also refers to minerals and metals from the earth, such as gold, silver, and iron.
