How is variation maintained in population?
A) Heterozygotes serve as a reservoir of recessive alleles.
B) Mutation generates new alleles.
C) Recombination and independent assortment during gametogenesis creates variation.
D) Gene flow brings in new alleles.
E) All of the answer choices describe ways that variation is maintained within a population.
Recombination
The process by which genetic material is physically mixed during sexual reproduction, leading to the production of offspring with combinations of traits that differ from those found in either parent.
Gametogenesis
The process by which gametes, the sex cells, are produced in the gonads (ovaries and testes) through a sequence of meiotic cell divisions and differentiation.
Genetic Variation
The diversity in gene frequencies within a population, caused by mutations, genetic recombination, and other factors.

Final Answer :
E
Explanation :
All of the answer choices describe ways that variation is maintained within a population. Heterozygotes serve as a reservoir of recessive alleles, mutation generates new alleles, recombination and independent assortment during gametogenesis creates variation, and gene flow brings in new alleles. Together, these factors contribute to the maintenance of genetic diversity within a population.
