Original Title: TIL In 1995, a boy was discovered with blood containing no trace of his father’s DNA due to an extremely rare case of partial human parthenogenesis, where the mother’s egg cell divided just prior to fertilization, making parts of his body genetically fatherless.

Interesting had not heard of three year old FD.

I hope he had a happy life, the case study the article referenced is from the University of Edinburgh back in 1993, and the article itself suggests celular defects in chimeric tests.

I get the implication that the article makes for novel stem cell pathways, but the suggestion for global genetic testing seems a little unrealistic. I'm not sure at what point researchers will ever be given unfettered access to everyone DNA, but given the current political/economic climate and the DNA genotyping industry (*cough23and me) not sure that will happen
