Q.Write notes on gene pool.

The gene pool represents the entire stock of genetic variation available within a population and is a foundational concept for understanding evolution.

Definition: a gene pool is defined as the sum of all genes and their various alleles present in the reproducing (interbreeding) individuals of a population at a particular time.

Significance:

• It represents the total genetic variability/diversity available within a population.
• Offspring inherit their genes from this shared pool via sexual reproduction, so the gene pool determines the range of traits possible in future generations.
• The relative frequencies of different alleles within the gene pool can change over time due to mutation, natural selection, genetic drift, and gene flow (migration) — this change in allele frequency over generations is the basis of evolution. …
