Question

Variations that confer an advantage to an individual organisms will survive in population. justify

Answer 1

Sol:
Variations are the changes caused in the genetic material thereby bringing about changes in the offspring. Variations caused by mutations can be beneficial or detrimental. Variations acquired by the individual are not easily acceptable.

*Only advantageous variations occurring in an individual are able to exist in population.
*The individuals which underwent variations would survive and pass on these variations to next generations. These individuals are called as variants.
*These variations carried over to many generations ccumulate in a population.
*This is because variations which are detrimental cause the death of the individual.

Hence, there is no chance for the detrimental ( variations causing death) variations to be carried to the next generation. Only advantageous variations can survive.
