Modes of Reproduction and Human Reproductive Characters

  • Asexual reproduction produces an offspring from a single organism without the formation of gametes.
  • Sexual reproduction produces offspring by the formation and fusion of gametes.
  • Gametes are specialised sex cells with a single set of chromosomes.
