Ans.
Genetic engineering involves manipulation of genetic material organisms to develop organisms with desirable characteristics. Natural selection involves selection of traits that make organisms better adapted to their surrounding environment, without human interference.
Both of the mechanisms involve transmission of genetic information form one generation to another as manipulated genetic material of parent organism is transmitted to next generation.
Both genetic engineering and natural selection select the traits that are most organisms with most beneficial to their environment.
Genetic engineering is faster than the process of natural selection. Natural selection is natural process and it works over generations, while genetic engineering involves desired modification of traits.
Both genetic engineering and natural selection work on all organisms, including humans.
Natural selection involves selection of individuals with beneficial traits for survival, while other individuals with less useful characteristics are wiped out. Therefore, natural selection does not work on entire population.
Thus, the options 1), 3), and 4) are correct.
