In the seychelles warbler, territorial behavior encourages a regular population dispersion pattern, and cooperative breeding encourages a clumped population dispersion pattern.
-Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat.There are three main types of dispersion: clumped, uniform and random.
-Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. Random dispersion individuals are arranged without apparent pattern
If an X-linked mutation results in the absence of a certain protein, a cell which has inactivated the wild-type, X-chromosome will experience problems from the protein absence, possibly resulting in growth disadvantage of that cell, or even cell death, which will result in selection against mutant cells
