Question in English:
The concept of gene flow is demonstrated when a cow is expelled from her herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these is most likely to increase?
A. Natural selection
B. Genetic variation
C. Environmental suitability
D. Reproductive mutations
Answer:
B. Genetic variation/Variación genética
Explanation:
When an organism from one population enters a new population that does not normally mix, it brings with it its own unique genetic variation.
Its new alleles are introduced into the new population when the cow breeds, enhancing the amount of gene variation in the new herd. This is how gene flow increases variation
