Thus the phenomena of sex chromosome aneuploidy point to the selective involvement of X-Y homologous genes: the features of Klinefelter's and Turner's syndrome etc are attributable to this small class. Paul S. All subjects were born and raised at the University of Virginia School of Medicine animal facility.
Aneuploidy is the presence of an abnormal number of chromosomes in a cellfor example a human cell having 45 or 47 chromosomes instead of the usual In aneuploidy, there is a noticeable change originated in cells, causing more or less chromosomes than normal, causing different types of genetic mutations or syndromes in the fetus.
It may be assumed that the phenomenon reflects an aberration in meiosis, and there is therefore reason to suspect that aneuploidies occur with a similar frequency in other species. Author manuscript; available what is sex chromosome aneuploidy in Rockhampton PMC Oct 8.
