Genome-wide maps of recombination and chromosome segregation in human oocytes and embryos show selection for maternal recombination rates

Eva Hoffman, Alan Handyside and colleagues generate genome-wide maps of crossovers and chromosome segregation patterns by recovering all three products of single female human meioses. They detect a reverse chromosome segregation pattern and selection for higher recombination rates in the female germ line and report chromosomal drive against non-recombinant chromatids at meiosis II.
