Gene flow is the quizlet
WebWhen gene flow occurred between populations of captive (hatchery-bred) and wild salmon in Oregon, what was the most important result? Allele frequencies in the wild population became more captive-like; average fitness in the wild population declined. Why is it accurate to say that gene flow is largely random with respect to fitness? Webwhat is gene flow The movement of alleles into or out of a population Genetic drift Is more likely to overwhelm natural selection when populations are small Gene flow may (choose all that apply) 1 remove alleles from a population. 2 reduce evolutionary change 3 promote evolutionary change 4 introduce new alleles to a population.

WebGene flow Can introduce new alleles into a population's gene pool A result of the movement of fertile individuals or their gametes Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, and the allele for purple flowers is dominant. Webthe males and females differ in distinct anatomical ways, such as body size, coloration, or plumage. Which of the following statements best describes what happens in gene flow? New individuals that join a population contribute their alleles to its gene pool.
WebGene flow is the transfer of genes between populations. Occurs through the dispersal of seed, pollen, or veg structures. Consequences of gene flow are problematic when crops are grown for seed production or biotech. In these cases there is a need for identity preservations. Classic example of identify preservation Web-Gene flow is most strongly present in asexual organisms. -Gene flow tends to reduce similarities among members of the same species. reinforcement Which process can increase the amount of genetic divergence between two populations? -gene flow -niche exploitation -reinforcement -sexual reproduction
