Y-Chromosome Testing Details
The Y Chromosome DNA test is used for establishing whether 2 or more individuals belong to the same paternal line. Women cannot be tested directly as they do not possess a Y Chromosome.
The Y Chromosome price includes:
2 male Individuals
The cost of the test also includes all Y Chromosome DNA test reports and correspondence.
Additional test participants included in the Y Chromosome DNA test should be charged at the rate specified.

The Y-Chromosome DNA Test
A chromosome is basically DNA that is coiled up
very tightly. The X and Y chromosomes determine the sex of an individual. Women
have two X chromosomes and men have one X and one Y.
At conception a female child randomly receives a
copy of either of her mother’s X chromosomes and she also receives a copy the X
chromosome belonging to her father.
A male child also randomly receives a copy of
either of his mothers X chromosome but this time receives a copy of the one and
only Y chromosome possessed by his biological father.
Due to this, the Y chromosome is passed on
intact to any male offspring, therefore the Y chromosome passed on by a
biological father to his son is exactly the same (except for random mutation)
as the Y chromosome he received from his father. He in turn received it from
his father and so on. In addition, the Y chromosome of biological brothers,
paternal uncles and male cousins will also be identical.
The Y Chromosome DNA test analyses 12 genetic
locations on the DNA strand. The allele (alternating form of DNA) at each
location is identified by a number. Males that are linked by a paternal line
should produce a DNA Profile (list of numbers) that match at all the locations
