Document Summary

Agent of evolution: any process that results in changes in the frequency of alleles present in populations. Non-random mating is not an agent of evolution bc it does not introduce new genes in an organism https://onedrive. live. com/edit. aspx/documents/biology?cid=4612573e81e7633b&id=documents&wd=target%28september. one%7caa4f95b0-28e4 1/10. The currency of natural selection, if u have more offspring than your competitor, your genes will survive. Adaptations: traits that increase the fitness of organisms relative to others without that trait. Wild type: the most common form of a gene in nature. Fixed allele: an allele that is present at a frequency of 100% in a population. There are no other alleles for that gene in the population, only one allele = fixed allele. Fixation: the process by which an allele increases in frequency until it is at 100% in a population. Either fixed at 100% or there is more than one allele there. Rare event (does not occur often in organisms) at any one location in the genome but.
