What is a gene pool?

A gene pool refers to the total sum of all genes and alleles present within a population. This concept encompasses the genetic diversity available for reproduction and evolution within that population. By considering the gene pool, one can assess the genetic variation that exists, which is vital for the adaptability and survival of the population in changing environments.

This definition highlights the importance of alleles, as variations of genes contribute to the genetic makeup of the population. A diverse gene pool increases the likelihood that some individuals within the population will possess traits advantageous for survival and reproduction, thus impacting evolutionary processes over time. Understanding the gene pool is crucial for studying population genetics and evolution, as it provides insight into how traits are inherited and how populations change.
