OK - I’m a little slow to understanding what you meant and what he’s referring to. He is referring to just the Y-chromosome mutations and you say he’s ignoring the whole genome, which fits with what you said. The links you provide are sequencing the entire genome.

However, for what he’s saying, do we need the entire genome? Why run into all these complicated mathematical problems when we know Y chromosome is inherited from a father who passes it down to his son and so on? Wouldn’t that yield a more accurate pedigree rate for each generation of males rather than sequencing the entire genome?
