In human genetics, Haplogroup L (M20) is a Y-chromosome haplogroup.

This haplogroup is associated with India. It is a descendant haplogroup of haplogroup K, and is believed to have first appeared approximately 30,000 years ago.

Haplogroup L is believed to have been associated with the first significant settlement of India. Its arrival may explain a strange phenomenon: prior to the arrival of haplogroup L, the two haplogroups [Haplogroup C (Y-DNA)? C] and [Haplogroup D (Y-DNA)? D] were associated with a great expansion along the southern Asian coast. Today, C is relatively scarce in India, and D is absent. However, the mitochondrial lineages corresponding to the same coastal migration do not show similar declines.

One explanation is that the newcomers from haplotype L may have taken wives from the southern coastal populations (thus preserving the matrilineal line), while killing or driving away their menfolk (thus reducing the frequency of haplotypes C and D).





The Complete Blood Type Encyclopedia is the essential desk reference for Dr. D'Adamo's work. This is the first book to draw on the thousands of medical studies proving the connection between blood type and disease.
