Document Summary
Macroevolution: large scale evolution, such as speciation event, that occurs over hundreds or thousands of generations. Microevolution: small scale evolution, such as changes in allele frequency, that occurs from one generation to the next. Total population: refers to all individuals within population. However, microevolution is concerned with those that can contribute and. Gene pool reproduce: all genetic material in population * (make better definition) Alleles can be dominant, recessive, or codominant: dominant: masks effect of another allele, recessive: masked, codominant: one allele isn"t dominant over the other, heterozygote: two alleles are different, homozygote: same two alleles. Calculating genotype frequency: population of 200. 18 are nn: divide # of individuals with genotype by total population. Calculate allele frequency by adding all m alleles by total number of alleles: this information can be used to detect evolutionary change. Reginald punnett: creator of punnett square. Some mutations are spontaneous some are induced.
