</span><span>Skeletal muscle contraction is one immediate effect of exercise on the muscular system. Other effects include higher blood flow to muscles and increased muscle temperature, Regular exercise increases bone width and density, strengthens muscles, tendons, and ligaments.

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.
