Mtdna in a sentence

Compared to Y-DNA, mtDNA is easier to extract and amplify from ancient specimens due to numerous copies of mtDNA per cell.

The remaining African Americans mainly belong to the paternal haplogroup I (~7%), which is also frequent in Northwestern Europe. citation mtDNA According to an mtDNA study by Salas et al.

The mtDNA is matrilineal and lets you trace your ancestry back through your mother, grandmother, great grandmother and so on.

Because the Y-DNA and mtDNA tests are more focused on one side of the line, you can get information going back farther, but with fewer data about family structure.

If a mother carries a mixture of mitochondrial DNA (mtDNA) types, this can make it hard to say which features their children will inherit.

Cell-level selection may then act to remove those cells with more mutant mtDNA, leading to a stabilisation or reduction in mutant load between generations.

Due to the lack of a system for checking for copying errors, mitochondrial DNA (mtDNA) has a more rapid rate of variation than nuclear DNA.

First, the 2011 paper relied on mtDNA SNPs derived from boxer and poodle genomes and used these to extrapolate inference about genetic variation within wild canids across the globe.

For example, an individual might have more than 85% Western European 'genomic' ancestry but still have a West African mtDNA or NRY lineage.

However, the Y-chromosome and mtDNA ( mitochondrial DNA ) testing processes for direct-line male and female ancestors can fail to pick up the heritage of many ancestors.

Initial studies of mtDNA cytochrome b sequence data suggested that the hierofalcons are basal among living falcons.

Mitochondrial DNA (MtDNA) studies have discovered a close link between Berbers and the Saami of Scandinavia.

One Natufian individual was also found to belong to the N1b mtDNA haplogroup.

The collection of mtDNA haplogroups sampled there differed significantly compared to their modern frequencies.

The earliest studies could only analyze segments of mtDNA, thus providing only broad correlations of affinity to modern 'West Eurasian' or 'East Eurasian' populations.

The mitochondrial DNA (mtDNA) of the polar bear diverged from the brown bear, Ursus arctos, roughly 150,000 years ago.

The presence of Arab Y chromosome lineages in the Middle East suggests that most have experienced substantial gene flow from the Arabian peninsula. citation mtDNA analysis The Maternal ancestral lineages of Arabic countries are very diverse.

The study deduced from genetic drift in nuclear and mitochondrial DNA (mtDNA) that giraffes from these populations are reproductively isolated and rarely interbreed, though no natural obstacles block their mutual access.

The three-spine stickleback provides an example of how molecular biogeographic studies that rely solely on mtDNA can be misleading, and that consideration of the genealogical history of alleles from multiple unlinked markers (i.
