Sampling Error and Founder Effect

The movement of genes between populations, preserving genetic variation

Occurs when a species undergoes a geographical change or is introduced to new areas by humans (correct)

Bias caused by small samples, decreasing as sample size increases

A drastic reduction in population size, leading to random changes in allele frequencies

Preservation of genetic variation between populations

Random fluctuations in allele frequencies (correct)

Increase in genetic variation within populations

Changes in average allele frequencies

Founder Effect

Bottleneck

Gene Flow (correct)

Genetic Drift
