Variations arising during the process of reproduction can be ______.

This question was previously asked in
RRB Group D 2018 Question Paper (11-Oct-2018) (Shift 3)
The correct answer is

Inherited

During reproduction, the process of DNA copying generates small differences (variations) among offspring. In sexual reproduction, the shuffling and combining of chromosomes from two parents produces even greater variation. When these variations arise in the germ cells (ova or sperm), they enter the zygote and are passed on to the next generation.

Because such variations are carried in the DNA that offspring receive from their parents, they are said to be inherited. Inherited variations form the raw material on which natural selection acts, driving evolution.

Words such as ‘altered’, ‘reduced’ and ‘modified’ may describe what happens to a variation later, but they do not capture the essential feature that variations produced during reproduction are transmitted from parent to progeny.

Hence, Inherited.
