Thirty healthy genetically modified babies were born after a series of experiments in the US. Out of the thirty born, two were tested and were found to contain genes from three parents. Fifteen of the thirty babies born were born in the past three years as the result of one experimental programe in New Jersey. These genetically modified babies were born to women who had problems conceiving. Before their eggs were fertilized, extra genes were inserted in an attempt to enable them to conceive. It is confirmed from fingerprints that these babies have three "parents": two women and one man. This means that those babies can pass their third set of genes onto their own children some day. Geneticists fear that this could be used to create new races of humans with higher intelligence or extra strength.
The women who had conceived these genetically modified babies were diagnosed as infertile. This is because they had defects in their mitochondria. Then, doctos took eggs from donors and sucked some of the internal material that contained healthier mitochondria and injected it into eggs from the woman wanting to conceive. This is the reason the babies have inherited DNA from three adults.
