We were able to detect traces of the human mitochondrial DNA (mtDNA) in urban sewage samples and to estimate the distribution of human mtDNA haplogroups. An expectation maximization approach was used to determine mtDNA haplogroup mixture proportions for samples collected at each different geographic ...
Human mitochondrial DNA haplogroup U is among the initial maternal founders in Southwest Asia and Europe and one that best indicates matrilineal genetic continuity between late Pleistocene hunter-gatherer groups and present-day populations of Europe. While most haplogroup U subclades are older than 30 ...

The mitochondrial DNA (mtDNA) control region is believed to play an important biological role in mtDNA replication. Large deletions in this region are rarely found, but when they do occur they might be expected to interfere with the replication of the molecule, thus leading to a reduction of m...
此外,在文章侧栏的名词解释中,对“haplogroup”的定义为A haplotype that is defined by binary markers, which is more stable but less detailed than one defined by microsatellites。其中,微卫星是指一类由串联的重复序列组成的重复DNA序列,长度为2-8个核苷酸。 它们可能是高度多态的,经常在群体遗传学研究中用...
Here we introduce a novel metadatabase YDHS that aims to provide such an interface for Y-chromosomal DNA (Y-DNA) haplogroups and sequence variants. The database uses ISOGG Y-DNA tree as the source of mutations and haplogroups and by using genomic positions of the mutations the database ...
We introduce a new calibration method of the mutation rate of synonymous transitions to estimate the coalescent times of mtDNA haplogroups.doi:10.1534/genetics.105.043901KivisildT.Genetics

An Alternative Model for the Early Peopling of Southern South America Revealed by Analyses of Three Mitochondrial DNA Haplogroups After several years of research, there is now a consensus that America was populated from Asia through Beringia, probably at the end of the Pleistocene. Bu... DSP Mic...
