TL;DR: A phylogenetic analysis of sex-chromosomal zinc-finger genes (Zfx and Zfy) indicates that the genes have not evolved completely independently since their initial separation.

TL;DR: An analysis of admixture in thirteen Mestizo populations from seven countries in Latin America based on data for 678 autosomal and 29 X-chromosome microsatellites found extensive variation in Native American and European ancestry among populations and individuals and evidence that admixture across Latin America has often involved predominantly European men and both Native and African women.

TL;DR: The study of RFLP all along the mtDNA and the analysis of nucleotide substitutions in the D-loop region of the mitochondrial genome apparently indicate that most or all full-blooded Amerindians cluster in one of four different mitochondrial haplotypes that are considered to represent the founder maternal lineages of Paleo-Indians.

TL;DR: Data is presented showing mitochondrial genome instability (mtGI) in most of the human cancers analyzed so far, and selectingive and/or replicative advantage of some mutations combined with a severe bottleneck during the mitochondrial segregation accompanying mitosis are the mechanisms probably involved in the origin of mtGI.

TL;DR: The ancestral founder haplotype, 0A, of the DYS199T lineage is identified and it is proposed that 0A is one of the most prevalent founder paternal lineages of New World aborigines.
