Field of study that looks into allele frequencies and how they change over time
Allele frequency
How common an allele is in a population
Gene pool
Consists of all the copies of genes in a population
Macroevolution
Evolution that happens over long periods involving big changes, like the creation of new species and groups
Population
Group of organisms of the same species living in around the same location that can interbreed
5 basic Hardy-Weinberg assumptions:
No mutations
Mating is random
No gene flow
Infinite population size
No selection
Hardy Weinberg equilibrium
When the gene, allele, genotype, and phenotype frequencies, will stay the same over generations (not evolving)
Non random mating
Cause of evolution when organisms prefer to mate with others of a certain genotype or phenotype, keeping populations from stable allele frequencies, and so from Hardy-Weinberg equilibrium
Gene flow
The movement of genes into or out of a population, sue to either movement of individual organisms or gametes (like spores or pollen). Could bring in new alleles or change the proportion of existing alleles.
