X-Chromosome Test

The x-chromosome is found in both females and males.  Females have a pair of two XX chromosomes and males have an XY chromosome pair.  Both the X and Y chromosome contain relatively little genetic material when seen in view of other chromosomes.  They contain repeated parts of DNA; the X-chromosome carrying about 2000 out of the 25000 or so genes, and the Y-chromosome about 78.  Females inherit an X-chromosome from the mother and an X-chromosome from the father. Thus, testing this chromosome is crucial when it come to determining relationships between females in DNA relationship testing and the genetic test involves mapping genetic profiles in X-Chromosome Testing.
