Geneticists must stop playing God

PARLIAMENT is currently debating the ethics of mitochondrial transference, which enables a woman with a faulty mitochondria in her egg cell to use the mitochondria of another woman's egg cell so that her offspring will survive.

The mitochondria contains genome material, so the child born will have genes from two women – two mothers, sort of.

This practice was discontinued after a few births in the US, because of some problem.

Those that have already been born and survive to breeding age will produce more offspring; or I should say, if they are fully human, marry to procreate. Do these geneticists have any idea what a child with three grandmothers may have to deal with?
