There should not be any changes in the gene pool.
In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.
Character displacement differs from resource partitioning because character displacement is directly linked to the evolution of genotypes that have allowed alternate resource use
<h3>What is
genotypes ?</h3>
An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. The number of copies of each chromosome found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene.
In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two alleles for each gene. Homozygous refers to a genotype when both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.
Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.
