Y Chromosomes of 40% Chinese Descend from Three Neolithic Super-Grandfathers
Demographic change of human populations is one of the central questions for delving into the past of human beings. To identify major population expansions related to male lineages, we sequenced 78 East Asian Y chromosomes at 3.9 Mbp of the non-recombining region, discovered >4,000 new SNPs, and identified many new clades. The relative divergence dates can be estimated much more precisely using ...
متن کاملHan Chinese males with surnames related to the legendary Huang and Yan Emperors are enriched for the top two Neolithic super-grandfather Y chromosomes O3a2c1a and O3a1c, respectively
Most populations now use hereditary surnames, and most societies have patrilineal surnames. This naming system is believed to have started almost 5000 years ago in China. According to legends and ancient history books, there were Eight Great Xings of High Antiquity that were the ancestors of most Chinese surnames today and are thought to be descended from the two legendary prehistoric Emperors ...
متن کاملAquarii : how CVs descend from supersoft binaries
AE Aquarii is a propeller system. It has the shortest spin period among cataclysmic variables, and this is increasing on a 10 yr timescale. Its UV spectrum shows very strong carbon depletion vs nitrogen and its secondary mass indicates a star far from the zero–age main sequence. We show that these properties strongly suggest that AE Aqr has descended from a supersoft X–ray binary. We calculate ...
متن کاملAneuploidy Assessment of X, Y, 18 Chromosomes in Sperm of Oligoteratospermia Using FISH Technique
Introduction: Not being to get pregnant, after one year of unprotected sex is called infertility. In the post, infertility was mainly a female problem, but the role of male factors in infertility has denotation, although a greater percentage of this infertility is related to the deficiencies of semen. Methods: This case-control study was performed on sperm samples from 30 infertile oligoterato...
متن کاملMelanesian origin of Polynesian Y-chromosomes
BACKGROUND Two competing hypotheses for the origins of Polynesians are the 'express-train' model, which supposes a recent and rapid expansion of Polynesian ancestors from Asia/Taiwan via coastal and island Melanesia, and the 'entangled-bank' model, which supposes a long history of cultural and genetic interactions among Southeast Asians, Melanesians and Polynesians. Most genetic data, especiall...
