how is hereditary changes responsible for evolution
Asked by aksabat1590 | 03 May, 2020, 09:15: PM
answered-by-expert Expert Answer
The offspring cells or organisms acquire the genetic information of their parents through a mechanism known as inheritance. The inherited traits undergo modification may be due to chromosomal abnormalities. Through hereditary, variations between individuals can accumulate and cause species to undergo evolution by natural selection.
