Which one of the following generates new genetic combinations leading to variation?

  1. Vegetative reproduction
  2. Parthenogenesis
  3. Sexual reproduction
  4. Nucellar polyembryony

Answer

(3) Sexual reproduction

Solution

Vegetative reproduction and nucellar polyembryony are asexual (no meiosis or fusion of gametes), so the offspring are genetically identical to the parent.

Parthenogenesis is development of an egg without fertilisation, so no new combination of genes from two parents is formed.

Sexual reproduction involves meiosis (crossing over and independent assortment) and fusion of male and female gametes.

Sexual reproduction generates new genetic combinations leading to variation.
