  • diploid - complete set of paired chromosomes from each parent (46 chromosomes [humans] )
  • haploid - single set of chromosomes (23 [humans] )
  • Gametes join at fertilisation to restore the normal number of chromosomes. The new cell divides by mitosis. The number of cells increases. As the embryo develops cells differentiate.
  • Sexual reproduction involves the production of gametes by meiosis. These then fuse to form a genetically unique individual.
