Chromosome probe can detect the fetus

The chromosomal chromosomes of the prenatal examination are difficult to determine the type of fetus. If the karyotype of the fetus is 46 chromosomes, including a X-stained mu and a small marker chromosome or a circular chromosome. , we have reason to think that this marker chromosome is a sex chromosome, but it is not certain whether it is Y or X. To further determine the origin of the second sex chromosome, a specific X or Y chromosome centromere probe can be used in conjunction with fluorescence in situ hybridization (FISll) for detection.
