Solution

The correct option is C
Natural selection

Any population has a built-in variation in characteristics. Those characteristics, which enable some to survive better in natural conditions (climate, food, physical factors, etc.), would outbreed others that are less-capable to survive under such natural conditions. Those who are a better fit in an environment, leave more offsprings than others. Therefore, they are known to be selected by nature.

Q. The process by which heritable variations enabling better survival, enable an organism to reproduce and leave greater number of progeny is called

Q. Consider the following statements:

1. Mutation is a change in the genetic structure of an organism.
2. Natural selection decides which mutations will live on and which ones will die out.
3. If the mutation is beneficial, the mutated organism survives to reproduce.

Which of the above is/are correct?

11. Consider the following statements,

1] Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce.

2] Greater the genetic diversity, the better is the population's ability to respond to pressures such as climate change and diseases.

Which of the above statements is/are correct?

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. (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.
