Population

Genetic drift

refers to the mechanism of evolution in which allele frequencies of a population change over generations due to chance.

sampling error in genetic drift

random fluctuations in allele frequencies, potentially resulting in reduced genetic variation.

bottle neck effect

is a phenomenon in which a significant reduction in population size leads to a loss of genetic diversity. This can occur due to events such as natural disasters or human activities.

founder effect

is a genetic phenomenon that occurs when a small group of individuals establishes a new population, leading to reduced genetic variation and different allele frequencies compared to the original population.

Genetic drift usually effects larger or small populations?

smaller, since they are more easily effected by changed in alleles.

Gene flow

The movement of individuals between populations causing an exchange of alleles between population

allele

a version of a specific gene

genotype

refers to the specific genetic makeup of an individual, encompassing all the alleles (versions of a gene) they carry.
