Located only a short distance off the southernmost shore of the Greater Indian subcontinent, the island of Sri Lanka has long been inhabited by various ethnic populations. Mainly comprising the ...

Y-chromosomal and mitochondrial DNA (mtDNA) polymorphisms have been used for population studies for a long time. However, there is another possibility to define the origin of a population ...

In addition, population geneticists have relied on mtDNA analysis to understand people’s histories and origins. However, some of mtDNA’s characteristics that make it useful also make people ...

Puerto Ricans, who have a high proportion of mitochondrial DNA of Native American origin, have more mitochondria-related nuclear genes of Native American origin than expected compared to genes ...

Therefore, most contemporary mtDNAs can be assigned to a continent of origin based on the nucleotide sequence of the most variable region (HvrI) of the mtDNA. The HvrI region is about 400 base ...

A vast wetland cradled our human ancestors To trace the geographic origin of our ancestors, Hayes and her colleagues examined mitochondrial DNA (mtDNA) from people living in southern Africa ...

Scientists have argued whether or not the often-studied mitochondrial DNA molecule is clonally inherited. It is with assuming clonal inheritance this type of DNA has been used to track the origin ...

Geneticist Eva Chan of the Garvan Institute of Medical Research in Australia and her colleagues say that mitochondrial DNA can be used to trace the origins of modern humanity to an area spanning ...

Essentially, they did discover mtDNA in the nuclear DNA of some children, which they call nuclear-mitochondrial segments (NUMTs). However, these “inserts” were not present in the parents’ DNA, meaning ...

The proportion of mutant mtDNA varies across patients and among ... with distinct developmental origins and proportions. Single-cell analysis of heteroplasmy in defined cell types has been limited ...

According to family history obtained by interview, none of the mutation carriers were related to one another, either genetically or by marriage. Two of them belonged to mtDNA haplogroup U ...
