The rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.
<h3>What is recessive allele frequency?</h3>
The recessive allele frequency refers to the initial frequency of a recessive allele in a population, which is masked in heterozygous individuals.
The recessive allele frequency depends on the adaptive fitness of this gene variant, the presence of selective forces and random mating, that facet its rate of change.
In conclusion, the rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.

B. Cell wall and a central vacuole
The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright. Animal cells are more fluid.
The central vacuole is a large region in the cell that stores nutrients and fluids. Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
Hope this helps!!
Environment can affect characteristics
inherited factors, so which genes the organism has and how it split and copies during meiosis, whether there was a mutation or not
