• B. Genes of an individual denotes the fitness of the gene pool.
• C. Individual genes lost are insignificant and does not signify the fitness of the gene pool.
• D. If the gene pool is not fit the species will go extinct.

Answer 1

The correct option is B Genes of an individual denotes the fitness of the gene pool.

Natural selection operates deciding which organism lives and which ones die. Even though individual genes denote the ‘fitness’ of an organism, natural selection always operates at the population level. It is the ‘fitness’ of the gene pool that helps in the survival of the species, individual genes that are lost are insignificant. It is when the ‘gene pool’ is not ‘fit’, that the species will go extinct.
