Men, not women, carry a Y chromosome, and it’s passed down father-to-son. Because the Y chromosome isn’t split and shuffled each generation, it’s a key signature for .

In human , the most commonly studied are Y-chromosome (Y-DNA) haplogroups and mitochondrial DNA (mtDNA) haplogroups, each of which can be used to define genetic .
mtDNA or Y-DNA changes only by chance mutation at each generation with no intermixture between parents’ genetic material.

Definitions 🧵:
A is a combination of that tend to be inherited together.
An is a variation of the same sequence of nucleotides at the same place on a DNA molecule.

pertain to a single line of descent. As such, individual membership of a haplogroup relies on a small proportion of the material possessed by that individual.

Mothers pass on mitochondrial unmixed to all their children; so the can be traced along the maternal line.

I was talking with a cousin; she finally did a test that showed what her haplogroup was & we discussed mine. My late mother tested with 23andMe in 2013 as did I; my daughter tested w/ in 2017 and @ LivingDNA. She tested at with a cheek swab & bought an extra for her daughter (my granddaughter) who was too young to fill a vial with spit at the time. All four generations show simply H as the haplogroup. My son tested @ 23andMe in 2017 and he is H3. How?
