L_4_10 — Sex Chromosome Evolution

Sex chromosomes — the genetic elements that determine biological sex in many organisms — represent one of the most remarkable stories in genome evolution. In mammals, the XX/XY system prevails: females have two X chromos

L_4_15 — Y-Chromosome and mtDNA Mismatch Patterns in Human Populations

The Y chromosome (paternally inherited, non-recombining) and mitochondrial DNA (maternally inherited) provide independent genealogical records of male and female lineage histories, respectively. When these two markers te

L_2_14 — Sex-Biased Admixture: Patrilocal vs. Matrilocal Migration

One of the most powerful revelations from ancient and modern DNA studies is that human migration, conquest, and admixture are almost never sex-neutral — they are systematically biased toward one sex or the other, produci
