Hello. This question is incomplete. The complete question would be:
"A farmer was growing the peas seen here: round and yellow are dominant traits; green and wrinkled are recessive traits. The farmer's goal was to produce a crop of round, green peas. To do this, she introduced plants that bred true for green seeds (peas). Over time the gene pool was modified and the presence of yellow peas became non-existent. This change in the gene pool is a result of hybridization. In scientific terms, we could call this a method of A) gene flow. B) emigration. C) niche shift. D) genetic drift.
"
Answer:
A) Gene Flow
Explanation:
Gene flow is nothing more than the movement of genes from one population to another. This can be seen in the question above, where the farmer introduced a population of plants that had the characteristic he wanted in the existing plant population with the goal of transferring genes from one population to another.
This flow, also called migration, is ensured by the insertion of new genes in a population thanks to the arrival of new individuals. Gene flow therefore ensures that populations are less genetically differentiated.
Gene flow is an important factor related to genetic variability. If an individual from one population migrates to another and inserts his or her gene into the population, if not an existing gene, it provides increased genetic variation.
