Y Chromosome. Almost every human has
46 chromosomes (23 pairs). 44 of these chromosomes are
non-sex chromosomes. The other 2 are sex chromosomes, the female has X, X (2 X
chromosomes), and the male has and X, Y.
The Y Chromosome is passed from generation to generation, father to son.
The DNA in the Y chromosome virtually remains the same in each generation,
meaning, the DNA will match even after many generations.
For genealogy purposes,
chromosome testing has become extremely significant to the study. This can
be interpreted as the surname DNA test; if you match with others, this proves a
relation. Your Y chromosome can tell you much more about your past.
Your Y chromosome gets slightly mutated through out the years. It can be many
generations before one mutation shows up on a
test analysis. This is due to the environment in which your blood line
This is how DNA researchers understand your family history path of
migration. There are
online databases that display other's DNA (with their permission), and allow
you to see who you match with. These DNA databases are growing everyday.
Everyone fits in a Haplogroup. A Haplogroup is a group of people with similar
DNA patterns. Here are the Y Chromosome Haplogroups.
You can take a DNA test to analyze your Y chromosome.
