In Klinefelter syndrome, the sex chromosome pairs which is either XX or XY don't separate in meiosis I in the male or female germ cell and this resulted in two gametes with a pair of X chromosomes and two gametes without X chromosomes.
Klinefelter综合征中,配对XX或XY性染色体对在父亲或母亲第次减数裂中有,从而产生了两有两条X染色体配子以及两有X染色体配子。
If failure also happens during meiosis in these germ cells as they give rise to gametes, other XXXXY, XXXY and XXYY genotypes that also lead to Klinefelter syndrome can result including the rare situation where there's an additional Y chromosome.
如果有丝裂和减数裂均发生了不,那么这类Klinefelter综合征患者基因型就可能是XXXXY,XXXY和XXYY等,包括了同时多出条Y染色体罕见情况。
