Answer:
This process adds new genes to a gene pool: A) Gene Flow
Explanation:
In this problem, it is required to study the new genes in the gene pool. Firstly, we need to study this concept.
The gene pool is the total of genes presented in a population as well as the combinations of genes that can occur. The composition of this gene pool can vary with time through the evolution process. For example Gene flow, also it is called gene migration, the introduction of genetic material from one population of a species to another.
Finally, we can conclude that this process adds new genes to a gene pool: A) Gene Flow
