Webfounder effect the result of starting a new population with a low number of individuals (founders), so that their GENE POOL may not contain the same proportions of ALLELES for a particular LOCUS as in the original population. For example, instead of containing three alleles of the ABO BLOOD GROUP locus, Australian aborigines contain no B alleles and … WebThe bottleneck effect is a type of genetic drift. Genetic drift is when the frequencies of alleles change in a population based on chance events. The change in frequency is totally random, and there is no pressure selecting for particular alleles. Genetic drift is different from natural selection, which is a process in which a population slowly ...
