these notes were taken during a class about biological evolution, but the subject title is missing.\n-results from immigration\n-new genes brought into a population\n-variation in a population increases\nwhat do the notes describe?\no gene flow\no natural selection\no genetic drift\no mutation
Answer
Brief Explanations:
Gene flow involves the transfer of genes from one population to another through migration, which brings new genes and increases population variation. Natural selection is about survival - of - the - fittest, genetic drift is random change in gene frequencies, and mutation is a change in DNA sequence. The notes match gene flow characteristics.
Answer:
gene flow
