Breaking News: 3 Parents



three parentsBREAKING NEWS! The first baby with DNA from three parents has just been born in Mexico. The mother carries the genes for a deadly syndrome that had already caused four miscarriages and her first two children to die. Scientists spliced the egg of a third donor parent together with the mother’s mitochondria and fertilised it with the father’s sperm.

The UK Government has agreed to the principle, but only if the specific procedure is safe. In this activity, students learn how it can help women with a serious inherited condition to have a healthy baby and why it is deemed so controversial. They use ethical arguments to decide whether they would recommend it to help a couple in need.

Learning objectives

  • Describe how to create an embryo with three parents, and explain how this technique could be used.
  • Make a decision about a new technology using ethical thinking.

    3 parents.

    Thanks for this thrilling activity. My students discovered the medical, ethical, sociological and technical aspects all together and they discuss in a very lively way almost forgetting the break. It was the first time I used this material and I really appreciated it.

    Good at promoting discussion

    I used this to promote discussion in high ability and low ability groups. They really produced a strong SMSC discussion so well worth the lesson time used.

    Peço desculpa por não escrever em Inglês.

    A atividade é muito interessante, pois permite aos alunos pensarem como a medicina pode remediar ” alguns” casos que resultariam em doenças graves.

    Do these resources exist yet?

    I might be being stupid but clicking on the available links does not give me access to anything I can use.
    The YouTube video link seems to be devoid of content too.
