Genetic variation and the Hardy-Weinberg proportions
The fundamental information about genetics for any individual is her genotype — the alleles that she has. But genes in populations can be considered in other...

Eye pigmentation and allele frequencies
Eye pigmentation in humans varies along a spectrum of colors from dark brown, through lighter brown, hazel, and green, to light blue. These differences are c...
Founder effect
A founder effect is caused by genetic drift in a small number of initial founders of a new population.
Genetic drift
If everyone in a population lived a long life, mated, and reproduced absolutely equally (two offspring per person), then the population size would never chan...
Genetic variation and the Hardy-Weinberg formula
The fundamental information about genetics for any individual is her genotype. The genotype for a single genetic locus is simply a list of two alleles, wheth...
