BIO- Evolution Vocabulary 21-40

Genetic drift that results from a devastating event that greatly reduces the population size and the diversity of genes in the population

• Subspecies

• Genetic drift

• Allopatric speciation

• Bottleneck Effect

Differences in a specific trait found within a population

• Speciation

• Genetic variation
