An individual and a population has following certain attributes like pattern of distribution. Dispersal biotic potential and gene pool. Phenomenon of distribution of individual within geographical boundaries of the population is termed as interpopulation dispersion or internal distribution patterns or dispersion.
Dispersal an individual is dispersed at one or another time during their life in a population which is revealed by immigration or emigration.
(i) Immigration is the number of individuals of the same species that have come into the habitat from elsewhere during a specified time period.
(ii) Emigration is the number of individuals of the population who exit or leave the habitat and go elsewhere during a specified time period.
Biotic Potential Biotic potential is the natual capacity of a population to increase its size under ideal environmental conditions.
Gene pool All the genotypes of all individuals in a breeding population is referred to as gene pool.
