  • A major part of the human Y chromosome consists of palindromes with multiple copies of genes primarily expressed in testis. Here, the authors investigate copy number variation in these palindromes based on whole genome sequence data from 11,527 Icelandic men.

  • Reconstructing the genome of an ancestor: 788 Icelanders are descended from a man who arrived there in 1802. 38% of his African mother’s genome has now been reconstructed from their pedigree and the genomes and genotypes of current Icelanders up to 8 generations later.

  • Agnar Helgason and colleagues report the point mutation rate for the male-specific euchromatic sequence of the Y chromosome based on 753 Icelandic males. They find that the non-recombining portions of the Y chromosome mutate at a faster rate than palindromic regions, suggesting that gene conversion acts to correct mutations in palindromic sequences.
