What concept describes the variation in the genotypes of a population?

• A. Genetic Drift
• B. Gene Flow
• C. Genetic Diversity
• D. Allelic Frequency

Answer: (C)

The concept that describes the variation in the genotypes of a population is genetic diversity. Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It is a measure of the variability or variety of genes within a population, which can influence how individuals within the population respond to environmental changes, diseases, and other pressures. Higher genetic diversity within a population often contributes to greater resilience and adaptability, as it increases the chances that some individuals carry alleles that may be beneficial under changing conditions. In contrast, populations with low genetic diversity may be more vulnerable to extinction due to their limited ability to adapt to new threats or changes. Other options relate to components or processes that can affect genetic diversity but do not directly describe the variation itself. For example, genetic drift refers to random changes in allele frequencies in a population, particularly in small populations, and gene flow involves the transfer of genetic material between populations, potentially affecting genetic diversity. Allelic frequency pertains to how common a particular allele is in a population but does not capture the overall variation in genotypes.
