Final answer:
No, migration does not always cause a Hardy-Weinberg disequilibrium. The Hardy-Weinberg principle describes a population in genetic equilibrium, where the allele frequencies remain constant over generations. Migration can introduce new alleles into a population, but it does not always result in a change in allele frequencies.
Step-by-step explanation:
No, migration does not always cause a HW (Hardy-Weinberg) disequilibrium. The Hardy-Weinberg principle describes a population in genetic equilibrium, where the allele frequencies remain constant over generations. Migration can introduce new alleles into a population, but it does not always result in a change in allele frequencies.
For example, if migrating individuals have the same allele frequencies as the receiving population, then migration will not disturb the genetic equilibrium and cause HW disequilibrium. It is important to note that migration is just one of the factors that can cause HW disequilibrium, along with natural selection, genetic drift, mutation, and non-random mating.
