Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition. Human gametes have 23 chromosomes, one each of 23 unique chromosomes. This is the n, or haploid, condition.
Genetic diversity is a biological term that explains the variations that exists in the genetic makeup of organisms in a population. It also ensures survival and prevents inbreeding effects.
The process that lead to an increase in genetic diversity include:
I. Random fertilization
III. Independent assortment of chromosomes
IV. Crossing over of alleles (I, III, and IV)
- These processes of random fertilization, independent assortment and crossing over ensures continued variation among populations.
- All these processes allows for the blending and mixing of the alleles to give a combination that is different (not identical) to that of the parents.

Answer:
Psychology is the academic discipline concerned with the inner life (knowing, feeling and striving) and the behavior of people. It generally does this by following the scientific method, but in some cases it makes use of symbolic interpretation and critical analysis, following the example of other social sciences.
The goal of psychology is to acquire knowledge about the behavior of humans, both in their everyday environment and under special circumstances. With the emergence of the behavioral movement, the object of psychology was reduced to the outwardly observable and measurable behavior of animals humans, because the inner life would not be objectively registered by scientific observation, but only subjectively by introspection and understanding. This limitation has been reversed, among other things by the 'cognitive revolution' in psychology, by the great social importance of psychotherapy and by the connotations that the word 'psychology' evokes in everyday language use.
