IGF binding protein-3, luteinizing hormone, and testosterone in 109 males with 47,XXY, 47,XYY, or sex-determining region of the Y chromosome (SRY)-positive 46,XX karyotypes" (PDF). J Clin
During a 3-year period in which 1500 amniotic fluid samples were studied, six cases of sex chromosome abnormality were detected antenatally: two with XXX, three with XYY and one with XXXXY sex chromosome constitution. After careful counselling, the parents in each case chose termination of the...
Dogs have a diploid chromosome number of 78. How many chromosomes do their gametes have? Why do prokaryotes need to have genetic variation? Explain the process of fertilization in the female human reproductive system How are genes and alleles passed down though generations?
A simple screening method for detection of Klinefelter syndrome and other X-chromosome aneuploidies based on copy number of the androgen receptor gene Due to the high prevalence and variable phenotype of patients with Klinefelter syndrome, there is a need for a robust and rapid screening method allo...
About 1:650–1000 children are born with an extra X or Y chromosome (47,XXX; 47,XXY; 47,XYY), which results in a sex chromosome trisomy (SCT). This international cross-sectional study was designed to investigate gaze towards faces and affect recognition
Public and scientific attention is given to the possible role of an extra Y chromosome in human aggression. A number of studies have supported the earlier finding of an elevated frequency of cases with an XYY complement among men in inst... HA Witkin,SA Mednick,F Schulsinger,... - 《Scie...
12 psychopathic patients with chromosome aberrations found among 480 individuals in two institutions for criminal psychopaths in Denmark have been crimino-biologically investigated. 5 of these individuals have Klinefelter's syndrome, 5 are of the XYY karyotype, 1 is 46,XY/47,XY ?Xq- mosaic, and ...
