Method Primary source [1] abstract:"[Researchers] conduct a study of genome-wide mutation rates by sequencing the entire genomes of 78 Icelandic parent-offspring trios at high coverage."
Comments P.467 right column bottom paragraph: "Kong and colleagues' study [primary source [1]] is by far the largest of its kind yet conducted, involving 78 Icelandic parent–offspring trios. Their estimate of 60 new mutations per generation is in agreement with previous calculations [primary source [2]], but their data also 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 de novo mutations transmitted by the mother is always roughly 15, regardless of her age."
