What term refers to all the genetic information in a breeding population?

The term that refers to all the genetic information present within a breeding population is "gene pool." This concept encompasses the complete set of genetic variations, including all the alleles for every gene present in the individuals of that population. The gene pool is critical for understanding genetic diversity, evolution, and how populations adapt to their environments over time.

The gene pool is a fundamental concept in population genetics and highlights the genetic potential for future generations. It allows researchers and biologists to assess the health and viability of a population. A larger and more diverse gene pool typically indicates a greater ability for a population to adapt to changes in the environment, resist diseases, and maintain overall resilience.

Other terms listed, like a gene bank, refer to collections of genetic material preserved for conservation and research rather than the entirety of genetic information in a breeding population. A genomic library is a tool used in molecular biology that contains cloned DNA fragments of an organism's genome, not the entirety of genetic variation in a population. A gene marker is a specific DNA sequence that is associated with a particular gene or trait, but it does not represent the entire genetic information of a population.
