||Primary source abstract:"[Researchers] conduct a study of genome-wide mutation rates by sequencing the entire genomes of 78 Icelandic parent-offspring trios at high coverage."
||"[Primary source researchers' data] reveal that, although a 20-year-
old father transmits, on average, approximately 25 mutations to his child, a 40-year-old father
transmits around 65. This means that every
additional year of paternal age results in an
average of two extra mutations in human
offspring. By contrast, the authors found that
the number of
by the mother is always roughly 15, regardless
of her age."
