Reproduction

There are 2 forms of reproduction:

• Sexual Reproduction
  • The joining (fusion) of male and female gametes
  • The mixture of the genetic information from two parents leads to a variety of offspring

• Asexual Reproduction
  • There is no fusion of gametes
  • Only one individual is needed as the parent
  • No mixing of genetic information - No genetic variation in offspring
  • The genetically identical individuls are CLONES

Mordern Cloning Techniques

• Tissue Culture 
  • Using small groups of cells from part of a plant 

• Embryo Transplants 
  • Splitting apart cells from a developing animal embryo before they become specialised
  • Letting them grow in a laboratory for a while
  • Then transplanting the identical embryo into host mothers

• Adult Cell Cloning
  • The nucleus is removed from an unfertallised egg cell
