When a preovulatory oocyte reinitiates meiosis, it sheds a cytoplasmic frag
ment containing mitochondria and redundant set of chromosomes. We have dete
cted DNA sequences from both the mitochondrial and nuclear genomes in polar
bodies from unfertilised human oocytes, demonstrating the feasibility of d
iagnosing mitochondrial diseases before conception.
