Which Condition Is Not Among The Requirements Of Hardy-Weinberg Equilibrium? Hardy-Weinberg equilibrium requires no immigration or emigration, a large population, random mating, and no spontaneous mutations (all of which are virtually unavoidable in nature). Natural selection would violate these conditions. What are the 5 requirements for Hardy-Weinberg equilibrium? Key points: When a population is in
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
What Factors Affect The Variations Of Gene Pools? What factors affect the variations of gene pools? There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection. Mutations create new genetic variations in a gene pool. How does gene flow affect gene pool? Gene flow within a population can increase the genetic
Does Genetic Drift Occur In All Populations? Does genetic drift occur in all populations? Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. In which
