WebNov 4, 2024 · Gene flow, or gene migration occurs when allele frequencies in a population change as organisms migrate into or out of the population. Migration from one population to another introduces new alleles into an existing gene pool through sexual reproduction between members of the two populations. WebSpecifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such...

WebDec 9, 2024 · Low genetic diversity means that there is a limited variety of alleles for genes within that species and so there are not many differences between individuals. This can mean that there are fewer opportunities to adapt to environmental changes. Low genetic diversity often occurs due to habitat loss.
