What is gene pool?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Gene Pool**: A gene pool refers to the complete set of genetic information (alleles) present in a population. It encompasses all the genes and their variations within that population.

2. **Composition of Gene Pool**: The gene pool includes all the alleles for every gene in a given population. This means that it consists of both dominant and recessive alleles, as well as variations that may not be expressed in the phenotype.

3. **Population Example**: Consider a population of organisms where certain traits are represented by specific genes. For instance, if we have a gene represented as "T" (which could denote a specific trait), the presence or absence of this gene in individuals of the population contributes to the overall gene pool.
