Study Notes

Population in Sociology and Geography

In sociology and population geography, the term 'population' refers to a specific group of people living in a particular area.

Etymology of 'Population'

The term 'population' originates from the Latin words 'populare', meaning 'to inhabit', and 'populus', meaning 'people'.

Lincoln Index in Ecology

The Lincoln index calculates the overlap between two species' ranges in ecology.

Population in Ecology

In ecology, 'population' refers to a group of organisms of the same species that live and interbreed in a specific geographic area.

Importance of Census in Population

Conducting a census is crucial in population studies as it provides data on population size, structure, and distribution.

Sexual Population in Ecology

The area of a sexual population in ecology refers to the geographic range within which individuals of a species can interbreed.

Interbreeding Population

A panmictic unit is a set of organisms in which any pair of members can breed together and exchange gametes.

Sewall Wright's Contribution

Sewall Wright, a geneticist, showed how allele frequencies can be converted to genotype frequencies by expanding an appropriate quadratic equation.

Inbreeding and Genetic Drift

The breaking up of a large sexual population into smaller overlapping sexual populations due to localization of gamete exchange is known as genetic drift.
The inbreeding coefficient (f or φ) quantifies the degree of inbreeding in a population.

Inbreeding Coefficient

The inbreeding coefficient (f or φ) measures the rise in homozygosity in a population due to inbreeding.

Inbreeding Depression

Inbreeding depression refers to the decrease in the mean phenotype of the gamodemes collection compared to the panmictic original.

Plant and Animal Breeding

The procedure that deliberately utilizes the effects of dispersion in plant and animal breeding is known as line breeding.
Line breeding leads to the greatest genetic advance and is more powerful than selection acting without attendant dispersion.

Isolation by Distance

Isolation by distance leads to small actual gamodemes that exchange gametes reasonably uniformly within themselves but are virtually separated from their neighboring gamodemes.
