摘要作者报告有多种先天性异常的染22症的活产女婴。
Polysomy, which includes trisomy, is the condition in which one or more chromosomes are represented more than twice in the cell.
多染包括染都是条或多条染代替了正常细胞中的两条染成的。
So this fetus presented seeral signs of trisomy 21, including the hypoplasia of the nasal bone, hypodontia, micrognathia, and hypospadias.

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，的方可能会贡献多于条染色，被称为三；或者少条染色，称为单。
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号染色三胎儿不能存活，要想存活就必须在胚胎早期丢失条染色，过程称为三染色自救。
So we know that people with Down syndrome have an extra copy of the 21st chromosome, which is why it's sometimes called trisomy 21.
因此，我们知道唐氏综合症患者拥有额外的第21号染色拷贝，就是为什么它有时被称为21三症。 “三” 意指三个，就像三轮车有三个轮子样。
And there's trisomy 13, 16, 18.
还有13号染色三、16号染色三、18号染色三。
