Genetics Flashcards
Genetic drift
The change in frequency of an existing gene variant in the population due to random chance. Can cause variants to disappear
Genetic diversity
Variation that occurs within a species
Migration
The movement of individuals alleles from one population to another population/gene pool
Immigration
The movement of individuals into one gene pool
Emmigration
The movement of an individual out of a gene pool
Natural selection
Process through which populations of living organisms adapt and change to their climate to ensure survival
Independent assortment
Each chromosome pair is independently sorted with the other pairs when they line up at the equator 1 homologous chromosome enters a gamete
Segregation
Every individual contains a pair of alleles for each particular trait which segregates (seperates) during meiosis
Crossing over
The exachange of dna between paired homologous chromosomes that occurs during meiosis
