write the importance of variation.
Answers
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. ... Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
Answer:
➸ DNA copying during reproduction is important for maintaining the body designs of the different organisms to survive in the existing environment.
➸ As the environment is constantly changing due to the change in temperature, climate, water level, etc.; as if the organisms cannot adjust themselves along with the changing environment, the species will get extinct.
➸ If there are variations in some individuals of a species they may be able to survive the changes in the environment.
➸ So variations is species is necessary for the survival of different species and for the evolution of the new species.
ADDITIONAL INFORMATION –
➸ The variations are only possible in sexual reproduction.
➸ Sexual reproduction is the type of reproduction in which two individual parents are involved.
➸ Reproduction is the process by which living organisms reproduce new individuals of the same species.
➸ It is necessary for continuation of the species and the survival of these species.
