How does reproduction help in providing the stability to the population of species?
Asked by | 7th Oct, 2008, 05:34: PM
Reproduction maintains the number of chromosomes specific to a species in each generation. Multi- cellular organisms have specialised cells in their gonads, which have only half the number of chromosomes and half the amount of DNA as compared to non-reproductive body cells. So when these germ-cells from 2 different individuals combine during sexual reproduction to form a new individual, it results in re-establishment of the number of chromosomes and the DNA content in the new generation. Thus it provides stability to the population of species. The consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use a particular niche that it inhabits.
