Answer 2

see genetic variation is the change in genes..
if there wont be any genetic variation then all organism would ave looked same and they wouldn't be surviving much due to no variation...
gnetic variation causes the chances of organism to survive in adverse condition..
just for ex
once there was a red beetle
yu know crows love beetles so the red beetle always became croes prey..
but suddenly there came a variation in a red beetle and it changed to green
this led to the camouflage of green beetles in bushes and they could not be seen .as a reslt the crow always attackes on red bettle..time came when there was no red bettle left and green beetle flourished..this is an ex of genetic variation...hope this helps
