Can Extinction Be Linked With Genetic Variation? Studies have repeatedly shown that rapid reductions in genetic diversity, as we are seeing in populations worldwide, increase the risk of extinction. By moving individuals between populations, and allowing those individuals to interbreed with local populations, we generate offspring with increased genetic diversity. How does genetic variation affect
Can The Same Trait Arise From Different Genetic Changes? Can the same trait arise from different genetic changes? Mutations could arise in the same gene and give rise to the same trait because many nucleotides contribute to controlling the expression of a gene. Mutations in a different gene could also give rise to the same
What Does Gene Flow Do To The Variation Between The Island And Mainland Populations? What does gene flow do to the variation between the island and mainland populations? Gene flow can counteract the effects of natural selection and genetic drift. It increases the genetic variation in a population (through the introduction of new alleles) and
