Bottleneck Effect: one type of genetic drift in which a natural disaster kills large numbers of a population regardless of fitness level & the surviving reduced population is likely to have a genetic makeup that is not representative of the original population; allele frequencies are unlikely to be identical to that of the original population
Practice creating chromosome maps by analyzing the frequency of crossing over in a set of genes located on the same chromosome. The recombination frequency provides clues to the location of the genes on a chromosome.
