Animal Cloning

• Embryo Transplants

  • Cells are taken from a prize bull and egg cells are taken from a prize cos
  • The sperm artificially fertilises the egg cell. The embryo that develops is split many times to form clones
  • These cloned embryos will be implanted into other surrogate cows to grow genetically identical offspring, which are ideal
• Adult cell cloning

  • Taking an unfertilised egg cell and removing its nucleus
  • The nucleus is then removed from an adult body cell and inserted into the empty egg cell
  • This is implanted into the womb of an adult female. It grows into a genetically identical copy of the original body cell and has the same genetic information
• Issues surrounding cloning

  • There is a reduced gene pool
  • Can be used to preserve and endangered species
  • Animals might not be as healthy
  • Humans may be cloned in the future
