A drastic reduction in population size; promotes genetic drift.
A measure of the relative contribution of a given genotype to the next generation.
Agent or causative force that results in selection.
Change in a single DNA Nucleotide.
Change in chromosome number of less than an entire genome.
Change in genotype other than by recombination.
Change in genotype solely by chance effects.
Evolution at the population level; change in allele frequencies over generations.
Evolution of chromosome number which is a multiple of some ancestral set.
Exchange of chromatid segments of two adjacent homologous chromosomes during meiosis (prophase).
Fitness of AA, if 80% in first generation and 40% in second generation.
Natural, shuffling of existing genes, occurring with meiosis and sexual reproduction.
One of the five conditions to maintain Hardy-Weinberg equilibrium.
Principle that the frequency of a gene / allele does not change over time (given certain conditions).
Rearrangements (including losses and gains) of large pieces of DNA.
Selection for both extremes, against the average/median condition.
Selection for elimination of the two extremes in a population.
Selection for one extreme, against the other extreme.
Selection resulting in greater reproductive fitness in certain individuals of one sex.
