What is Y-chromosome testing? We learn sometime in our early years of school that the human body is made of Y chromosomes and X chromosomes. These are the sex chromosomes that determine and individual’s biological sex. It is Y-chromosome testing that determines the father of a child, a process used when there is dispute or doubt.  So, where do these X and Y chromosomes come from? The female inherits an X chromosome from the father, resulting in a XX genotype. The male inherits a Y chromosome from the father, resulting in a XY genotype. The mother only passes on the X chromosomes, so it is ..read more

When there is a dispute of a child’s parentage, the biological mother and the supposed biological dad often have to submit to court approved DNA testing. Simply stated, DNA testing is proof of paternity for fatherhood and by establishing that paternity, the father will have legal obligations and legal righ ..read more
