The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
<h3><u>Explanation</u>:</h3>
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
