염색체 이상: 두 판 사이의 차이

대부분의 염색체이상은 난자나 정자에서의 사고에 의해서 발생한다, 따라서 이상은 신체의 모든 세포에서 나타나게 된다. 그러나 일부 이상은 can happen after conception, resulting in [[Mosaicism]] (where some cells have the anomaly and some do not). 염색체 이상은 can be inherited from a parent or be "[[de novo]]". This is why chromosome studies are often performed on parents when a child is found to have an anomaly. If the parents do not possess the abnormality it was not initially [[Biological inheritance|inherited]]; however it may be transmitted to subsequent generations.
