Question

According to Neo-Darwinism variations, the raw material of evolution occur

• A. In an individual and remain restricted
• B. In gene pool of a population
• C. In all the membranes of one species
• D. In all the membrane of all species

Answer 1

Answer: (B)

In gene pool of a population

In Neo-Darwinism (fusion of natural selection and genetic concepts of Mendelism) which is also called as ‘modern synthesis’ theory of evolution. It states that natural selection is the process by which individuals with genetic traits better adapted to their environments survive long and reproduce to produce many offspring and so transfers the genes for those favourable adaptations to the next generation forming gene pool (collection of all genes of interbreeding population makes gene pool). The individuals lacking the favourable traits have fewer chances of survival before they can reproduce, thus removing their genetic material from the continuing gene pool. Thus, the correct answer is 'In a gene pool of the population.'
