Why is it accurate to say that gene flow is largely random with respect to fitness?
Group of answer choices

Alleles don't move by themselves- - individuals have to move.

Because it makes allele frequencies in the affected populations more alike (more homogeneous).

Because genetic drift occurs when gene flow occurs, and drift is strictly random with respect to fitness.

Individuals "just arrive"- - they don't necessarily carry alleles that are beneficial, deleterious, or neutral in the new environment.

Accepted Answer

∻Answer∻ ⚹ The correct answer is: "Individuals 'just arrive' - they don't necessarily carry alleles that are beneficial, deleterious, or neutral in the new environment." ⚹ ∻Solution∻ ‖ a ⋮ Gene flow refers to the transfer of alleles or genes from one population to another. It is an important mechanism of evolutionary change and is largely random with respect to fitness because it involves the movement of individuals and the alleles they carry without regard to whether those alleles are beneficial, deleterious, or neutral in the new environment. ‖ ∻Key Concept∻ ⚹ Gene flow is random with respect to fitness because it involves the movement of alleles due to the migration of individuals, not the selection of specific alleles based on their adaptive value. ⚹ ∻Explanation∻ ⚹ The randomness of gene flow with respect to fitness is due to the fact that when individuals migrate, they carry a random assortment of alleles, which may not necessarily provide any adaptive advantage in the new environment. This process can increase genetic variation within a population but does not directly select for alleles that improve fitness. ⚹◊How does gene flow contribute to genetic variation within populations?⍭ Generate me a similar question◊
