If all the members of a population are homozygous for the same allele, that allele is said to be:
Correct answer: D. Fixed in the gene pool
- A. Random in population's pool
- B. Random in a species
- C. Fixed in population's pool
- D. Fixed in the gene pool
Explanation
Explanation:If all individuals in a population are homozygous for the same allele, then that allele is fixed in the population's gene pool, meaning that it is the only allele present for that particular trait in the population.This option is not correct. If all individuals in a population have the same allele, then that allele is not random in the population's gene pool; rather it is fixed.This concept of an allele being random in a species does not make sense because alleles are specific variations of genes that exist within a population, not across an entire species.If all the members of a population are homozygous for the same allele, that allele is said to be fixed in the gene pool, not fixed in the population pool.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
