    Question Do haplogroup mutations usually just occur in only one, or a whole population of sperm cells inside the father's testes?

    I have been wondering about this for so long. Do those haplogroup mutations usually only occur in ONE of the father's sperm cells? So you can have two brothers in the same family carrying two different Y haplogroups, even if they are biological brothers by blood, both paternally and maternally...

    90% of species on Earth today came into being 100,000 to 200,000 ybp

    Found this on Phys.org: Sweeping gene survey reveals new facets of evolution "Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge? And who would have thought to...

    Mutation in Coenzyme Q gene defines most major mtDNA haplogroups

    While analysing the mtDNA phylogeny, I noticed that most of the common, successful mitochondrial haplogroups were defined by a new mutation in the Coenzyme Q - cytochrome c reductase gene (MT-CYB) encoding the Cytochrome b protein, located between positions 14,747 and 15,887 in the mtDNA...
