migrations

random chance

bottleneck events

small population

Homework Answers

Answer #1

Ans.

  • The process where a population's allele frequencies get altered by chance, solely due to the sampling error throughout the generations.
  • It is a random event taking place into the population genetics of animals.
  • Genetic drift can introduce drastic modifications in populations over a small time period.
  • There are many factors involved, leading a population toward genetic drift.
  • These factors include ;
  1. Random chance
  2. Bottleneck events
  3. Small population
  • It is a random event that may result in the alleles fixation or genotypes in populations.
  • Inbreeding co-efficient and homozygosity is enhanced due to removal of alleles in genetic drift.
  • Even though it happens all the time but ,populations which face regular extinction and recolonization cycles, are the frequent victims of genetic drift.
