Gene flow occurs
WebThat’s because when organisms reproduce sexually, some genetic “shuffling” occurs, bringing together new combinations of genes. For example, you might have bushy eyebrows and a big nose since your mom had genes associated with bushy eyebrows and your dad had genes associated with a big nose. These combinations can be good, bad, or neutral. WebThe concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these most likely increases? answer choices natural selection genetic variation environmental fitness reproductive mutations Question 12 30 seconds Q.

WebThe environment may impose an external barrier to reproduction, such as a river or mountain range, between two incipient species but that external barrier alone will not make them separate, full-fledged species. Allopatry may start the process off, but the evolution of internal (i.e., genetically-based) barriers to gene flow is necessary for speciation to be … Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration . While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur.
