Problems During Later Development/ High Failure Rates

The problems during later development are:

  • Much larger at birth (large offspring Syndrome)
  • Very large organs
  • Breath problems
  • Blood flow problems
  • Kidney malformations
  • Brain malformations
  • Impaired immune system

< >


High Failure Rates:
  • Somatic Cell Nuclear transfer is inefficient which means for every 1000 tries only 1 - 30 clones are made (970 - 999 failures in 1000 tries).
  • The egg and nucleus are not right for each other causing  failures
  • Egg might not divide or developed properly
  • Implanting the embryo into the surrogate mother could fail
  • Pregnancy could fail
  • Most of the eggs died without dividing once.
  • Many embryos die with in five days
