Evolution Biology flashcards | Quizlet from o.quizlet.com 2020 yet oaks form what is called a syngameon, in which ecologically and physically distinctive species persist in spite of ongoing gene flow. In population genetics, gene flow (also known as gene migration or allele flow) is the transfer of genetic material from one population to another. Year 10 biology, term 3.
Gene flow is the exchange of alleles between two or more populations.
Gene variations refer to the differences of genetic makeup in organisms of a population. Show declension of gene flow. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective. In population genetics, gene flow (also known as gene migration or allele flow) is the transfer of genetic material from one population to another.
