Answers
Answer all variations in a species don't have equal chances of survival.
Explanation:certain variations in a species which can better adapt itself to it's environment i.e. gets naturally selected only have greater chances of survival.
On the other hand , those variations which prove to be lethal for that species ,like if any halophile loses it's ability to tolerate extreme salinity as a result of variation, then that particular variation fails to get naturally selected and thus have negligible or fairly low chances of survival.
Answer:
No, all variation in a species do not have equal chances of surviving in the environment in which they find themselves. Depending upon the nature of variations, each individual would have different advantages of survival.
