  1. What is artificial Embryo Twinning? Krine Mélanie Massiquot Quentin Xavier Elodie BIO AC 1 2014-2015

  2. Wewill compare artificialand naturalsystems • Withartificial bissection : • -Bissection of artificialembryosafterfertilisation ( 2 methods ) • Withnaturalbissection : • -Whatis the difference between true twinsand false twins

  3. Bissection artificial: -Bissection of an embryo2 days after fertilisation -Bissection of an embryo5 to 7 days after fertilisation

  4. Artificial bissection : (In vitro) Newborns are genecallyidentical

  5. The Natural Process

  6. IdenticalTwins (monozygotic)

  7. Some figures : • Between 1979 and 2009, twin births increased by 79% • late 2009 -210,693 families had at least multiple births: in 98% of cases, it resulted in twins • France has among its population, not less than 2 million twins

  8. Dizygotic or Heterozygoustwins • Calledfraternaltwins • Difference: simultaneity of gestation • Eachdissimilargeneticheritage (differentgenes) • Can be of a differentsex or of the samesex

  9. Conclusion : This technique : artificial embryo twinning allows to amplify opportunities for reproduction (in cases of infertility for example)
