Sometimes though, one parent might contribute one chromosome too many, which is called trisomy, or one chromosome less, which is called monosomy.
但是有时候，双亲方可能会贡献多于条染色体，这被为三体；或者少条染色体，为单体。
Since trisomy 15 isn't compatible with life, the fetus only survives only if they lose one copy of the chromosome in the early embryo, called trisomy rescue.
15染色体三体胎儿不能存活，要想存活就必须在胚胎早期丢失条染色体，这过程为三染色体自救。
