Genetic drift produces variation for evolution when ________ (A) a gene pool decreases because a smaller group establishes a new population (B) chance events cause allele frequencies to fluctuate unpredictably (C) sudden change in environment drastically reduces the gene pool (D) a population has heritable traits better suited to the environment

Respuesta :

The correct option is (B) Chance events cause allele frequencies to fluctuate unpredictably

Genetic drift is the arbitrary change in the frequency of a gene variant in a population.

How can genetic drift influence evolution?

  • Genetic variety may be hampered by genetic drift, which may cause gene variations to completely disappear.
  • Additionally, it has the ability to greatly increase the frequency and potentially repair previously rare alleles.
  • Genetic drift may result in the loss of rare alleles, which can potentially shrink the gene pool.
  • The fact that genetic drift can also make a new population genetically distinct from its ancestral population supports the theory that it aids in the creation of new species.
