What is maternal haplogroup H1?

Haplogroup H1 is a branch on the maternal tree of human kind. The woman who founded this line lived between 9,000 and 10,800 years ago (Behar et al., 2012b).

What does it mean when you share a maternal haplogroup?

Any set of individuals who share a mother (that is, siblings or maternal half-siblings) have the same maternal haplogroup. In addition, all sons inherit their Y chromosomes from their biological fathers; a father and his son therefore share a Y chromosome or paternal haplogroup.

How common is H haplogroup?

Haplogroup H is the most common mtDNA clade in Europe. It is found in approximately 41\% of native Europeans.

What is the H chromosome?

In biology, homologous chromosomes are paired chromosomes. They essentially have the same gene sequence, loci (gene position), centromere location, and chromosomal length. Although they may have the same genetic sequence and loci, they may differ in alleles.

What does H mean in DNA?

Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup. The haplogroup has also spread to parts of Africa, Siberia and inner Asia. Today, around 40\% of all maternal lineages in Europe belong to haplogroup H.

Where is haplogroup H most common?

Haplogroup H is the most common mtDNA clade in Europe. It is found in approximately 41\% of native Europeans. The lineage is also common in North Africa and the Middle East. The majority of the European populations have an overall haplogroup H frequency of 40–50\%, with frequencies decreasing in the southeast.

How do you determine maternal haplogroups?

Maternal Haplogroups Maternal haplogroups are determined by defining variants in your mitochondrial DNA. Everyone inherits their mitochondria from their mothers. Unlike your other pieces of DNA, your mitochondrial DNA is the only type of DNA that is found outside of the nucleus.

What ismtmtdna haplogroup H?

mtDNA haplogroup H can be found within as much as 40\% of European people, making it the most common maternal haplogroup in the west. It is also commonly found in North Africa, the Middle East, Central Asia, and Northern Asia.

What is the distribution of haplogroup H in Europe?

Geographic distribution. Haplogroup H is the most common and most diverse maternal lineage in Europe, in most of the Near East and in the Caucasus region. The Saami of Lapland are the only ethnic group in Europe who have low percentages of haplogroup H, varying from 0\% to 7\%.

How far back can you trace maternal haplogroup B4’5?

The ability to trace back a person’s maternal haplogroup back so far – more than 50,000 years in the case of B4’5 – has to do with how it is passed down to each of us from our mother, and her mother, and her mother’s mother, and so on back in time. Maternal haplogroups are determined by defining variants in your mitochondrial DNA.
