Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.
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.
