how do organisms whether reproducing sexually or asexually maintain a constant chromosome number through several generations? Explain with the help of a suitable example.
The chromosome number has to be maintained in all the organisms. For this the asexual and sexual reproduction maintain a constant chromosome number by adopting different methods. ... In case of sxual reproduction, gametes are formed which are haploid in nature and then unite to restore the normal diploid condition .

Answer:
The populations of organisms live in well defined places (niches) in ecosystem, using their ability to reproduce. So, the consistency of DNA copying during reproduction is important for the maintenance of body design features that allow the organism to use that particular niche.
In sexual reproduction, organisms produce gametes by meiosis and they are haploid that is chromosome number is reduced to half. Gametes (haploid) fuse to make zygote (diploid) and so the original number is restored in case of humans.
