Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

Researchers from Johns Hopkins University and the University of Copenhagen analyzed over 139,000 embryos and identified variants in key meiosis genes, such as SMC1B, that influence chromosomal ...

By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than half of human conceptions survive to birth. The research uncovered the ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Homologous recombination (HR) is a universal DNA repair mechanism that faithfully restores genomic integrity following double-strand breaks (DSBs) in DNA. The details concerning the transfer of ...
