[QUOTE]Originally posted by Bettyboo: [QB] [QUOTE]Originally posted by Supercar: [qb] Simply put: A male person will receive his father's line of ancestry almost intact, unless until of course, a UEP occurred somewhere down the road. Even then, the father's ancestral line genetic data isn't lost. What would not be revealed about any other Y lineage, is that from the mother's side. This is where the mother's mitochondrial lineage reigns in. The mitochondrial lineage is generally received only from the mother. Here too, one can trace the person's maternal line almost intact. Any potential additional info about the said male's recent ancestry composition, like that of the person's grandfather from the mother's side and the person's grandmother from the father's side [whose Y chromosome marker and mtDNA marker are lost respectively] via immediate paternal and maternal ancestry, might be acheived via autosomal analysis. Both a male and female receive mtDNA only from the maternal parent. And since, females don't normally carry Y chromosomes, they don’t receive it from their father. So the father’s line of ancestry via Y chromsome is lost in a female offspring, but autosomal analysis will quite likely make up for that loss in another way. Autosomal test can only take one as far as the much more recent lines of ancestry, and thereafter, generally looses its usefulness as 'biohistoric' marker; this vacuum is filled in by the Y chromosome and mtDNA markers. [/qb][/QUOTE]This is what was explained to me. I was told that the Mitochrondial DNA goes unchanged from Mother to daughter. [/QB][/QUOTE]
