Q. According to the chromosomal theory of inheritance, which of the following type of cell division contributes maximum for recombination and genetic variation?

Q. (A)The effects of genetic drift are most apparent in small populations.
(B)Evolution and natural selection is most prominent in populations having no variations.

Q. Assertion: Hardy-Weinberg principle states that in the absence of disturbing influences, gene frequencies of large populations of sexually reproducing organisms do not change, provided that matings, occur at random.

Reason: The disturbing influences include mutation, gene flow, genetic drift, genetic recombination and natural selection.

Q. Which is most common chromosomal aberration seen in cancer-

Assertion (A): Differences in a population are created by genetic variations.

Reason (R): Driving factor for variation is the source of sexual reproduction and also asexual reproduction.
