Pertaining to genetic information that will not be passed on to offspring and therefore will not contribute to the gene pool of the species and its diversity. This is usually a result of an organism being unable or unwilling to reproduce.
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how these factors affect populations in an ecosystem...
