Answer
(iv) They get mixed instructions (genes) from both parents.

Explanation

  • In sexual reproduction, gametes come from two parents.
  • Each gamete carries a different set of instructions.
  • These mix in different ways for each child.
  • So offspring are different from their parents and each other.
Mixed genes from two parents make each child unique.
