Population

A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.

In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area. The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border.

In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population.

Population genetics (ecology)

In population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same of species, such as humans. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.

Population (album)

Population is the second studio album by Canadian indie rock band The Most Serene Republic. It was recorded and mixed by Ryan Mills, Mike Kuehn and Ryan Lenssen at Sleepytown Sound in Toronto. The album was released on October 2, 2007 through Arts & Crafts. This is the first album to feature the band's new rhythm section of Tony Nesbitt-Larking and Simon Lukasewich. The album artwork features the Muji toy "suburbia in a bag".
