Although sexual reproduction is a long-drawn,energy-intensive complex form of reproduction,many groups of organisms in Kingdom Animalia and Plantae prefer this mode of reproduction. Give at least three reasons for this.

(N/A) Sexual reproduction generates genetic variation in the offspring.
$(b)$ Since gamete formation involves meiosis,genetic recombination occurs during crossing over (meiosis-$I$),which leads to variation in the $DNA$ of gametes.
$(c)$ Organisms produced through sexual reproduction have better chances of survival in a changing environment due to the presence of diverse traits.
