Question

Offspring formed due to sexual reproduction have better chances of survival. Why? Is this statement always true?

Prabhat Rajore · Accepted Answer

The offspring formed due to sexual reproduction show variations because it involves fusion of two gametes. Due to crossing over during gametogenesis, random segregation of gametes or random fertilization more variations are there. These differences produced in offspring help the organisms to adapt well and increase chances of survival. whereas the asexual reproduction involves only one parent and the progeny is a clone , so there are no variations.

It is not always true that sexual reproduction has an advatage over asexual reproduction. Sometimes when the organism has well established in a suitable environment asexual reproduction is more efficient because it requires less energy, no need to search for mate and is less time consuming.
