Haplogroup mtDNA D descend from Dravidian Haplogroup M mtdna is the modal mtDNA haplogroup among northern East Asians. Among these haplogroups, D, B, F, and A were predominant in the Northern Han, with frequencies of 25.77%, 11.54%, 11.54%, and 8.08%, respectively.
The Han Chinese, alternatively the Han people [a] or simply the Chinese, [18] are an East Asian ethnic group native to Greater China. With a global population of over 1.4 billion, the Han Chinese are the world's largest ethnic group, making up about 17.5% of the world population.
[citation needed] Although Haplogroup O-M119 occurs only at an average frequency of approximately 4% among Han populations of northern China and peoples of southwestern China and Southeast Asia who speak Tibeto-Burman languages, the frequency of this haplogroup among the Han populations of southern China nearly quadruples to about 15-23%.

Y-DNA haplogroup migration in East Asia. The tables below provide statistics on the human Y-chromosome DNA haplogroups most commonly found among ethnolinguistic groups and populations from East and South-East Asia .
These haplogroups account for 52.7% and 33.85% of those in the Northern Han, respectively. Haplogroup D is the modal mtDNA haplogroup among Northern East Asians. Among these haplogroups, D, B, F, and A were predominant in the Northern Han, with frequencies of 25.77%, 11.54%, 11.54%, and 8.08%, respectively.
A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1] [2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation.

In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
