Question

Which of the following best defines a gene pool?

the sum of all genetic traits in a population’s individuals at a given time
any movement of genes from one population to another
any movement of organisms from one environment to another
the random change in the frequency of an allele in a population

Answer 1

The sum of all genetic traits in a population’s individuals at a given time

Step-by-step explanation:

The gene pool can be defined as the sum of all genetic traits in a population’s individuals at a given time. This term is used when we talk about genes found in a population of any species. It doesn't matter if we talk about us, humans, or, for example, certain species of ants, trees, or algae.

When it comes to the survival of a species, it's better if it has a larger gene pool. If a genetic pool is large, there is a lot of diversity and the population of a species has better chances of surviving environmental stress that may impact it.
