Question

How is the stability of DNA of a species ensured in sexually reproducing organisms

Answer 1

DNA is the hereditary material of all the organisms. So, it is necessary for the organisms to ensure DNA stability to maintain their species integrity.

Answer 2

Sexual reproduction involves fusion of two gametes i,e. male gamete and female gamete to form the offspring. Hence to maintain a stability of DNA, the number of chromosomes is halved during the process of formation of gametes . So, on fusion of two gametes,we get same number of chromosomes as that of the parent.

• The process of producing new individuals of the same species by existing organisms of a species is known as Reproduction.
• Sexual Reproduction helps in providing stability to the population of species by giving birth to new individuals as the rate of birth must be in control as compared to the rate of death to provide stability to the population.
