The more complex the translocation the less likely it is de novo because of all the steps involved, or the more complex it is the less likely it is inherited because meiosis is more difficult to be successful. Do you know of any studies that addressed this? Allen.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
