Higher organisms have resorted to sexual reproduction inspite of its complexity. Why ?

Solution

Higher organisms have resorted to sexual reproduction inspite of its complexity because sexual reproduction provides many advantages. They are :

1. The fusion of gametes and genetic recombination, causes variations in the offsprings thus, also forms the raw material for evolution.

2. The offsprings adapt more comfortably and quickly to the changes in environmental conditions and the survival rate is high.

3. Any mutation or disease present in the parents may not appear in the progeny due to variation in genes.

4. Sexual reproduction plays an important role in the origin of new species.
