Most (but not all) species Submitted by Angie on Sun, 06/07/2009 – 13:40. Most (but not all) species have a standard karyotype. The normal human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes. Normal karyotypes for females contain two X chromosomes and are denoted 46,XX; males have both an X and a Y chromosome denoted 46,XY. Any variation from the standard karyotype may lead to developmental abnormalities. So the 46,XX is normal. The 9qh+most probably represents a duplication of the heterochromatic secondary constriction in chromosome No. 9. Research indicates that such duplications might give an increased risk of chromosome abnormalities. For a better understanding of the karotypes and what this means for you, make an appointment with a genetic counselor. At 41, make an appointment as soon as possible so you can determine the best course of action. Best, Angie Login or register to post comments Need Help?
