If assertion is true but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - B Meiosis involves exhange of genes between homologous chormosomes. So, the gametes produced are genetically different from each other. Offspring produced by the fusion of gametes also show recombination of genetic variations. These variations in the offspring make organisms more adaptable to the enviroment and these have a definite role in evolution.
