Of particular interest is the use of genetic data in conservation biology. By definition, endangered and threatened species have reduced population sizes, making them subject to the vagaries of genetic drift and also to inbreeding. Inbreeding is mating between genetically related individuals, and ...
In biology, population simple means the number of individual organisms within a species. In human geography, it more often refers to the number of people living within a specific space. It could mean the population of a town or the worldwide population of humans on Earth....
population differences. Since it's easier to calculate the average within-population contribution (simply the mean heterozygosityH¯calculated over all within-populationHvalues), and since the between- and within-population contributions together sum toHT, the definition of FSTis then(HT−H¯)/...
Neyman and Pearson were able to solve this problem (i.e., to determine which test is best by this definition) for simple cases, and later work extended their results in various ways to more complex cases. As Fisher would point out in his relentless opposition to these ideas, the ...
Population growth, in population ecology, a change in the number of members of a certain plant or animal species in a particular location during a particular time period. Factors affecting population growth include fertility, mortality, and, in animals,
