An autotroph is an organism that prepares its own food using simple organic materials whist a heterotroph is an organism that cannot prepare its own food but depends on other organisms for survival.
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.
