Question

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

❇️Although sexual reproduction involves more time and energy, higher organisms have resorted to sexual reproduction in spite of its complexity.

❇️This is because this mode of reproduction helps introduce new variations in progenies through the combination of the DNA from two (usually) different individuals.

❇️These variations allow the individual to cope with various environmental conditions and thus, make the organism better suited for the environment.

❇️Variations also lead to the evolution of better organisms and therefore, provide better chances of survival.

❇️On the other hand, asexual reproduction does not provide genetic differences in the individuals produced.
