2006 National DNA Day Online Chatroom Transcript
This is just one question from an archive of the National DNA Day Moderated Chat held in April 2006. The NHGRI Director and many genomics experts from across NHGRI took questions from students, teachers and the general public on topics ranging from basic genomic research, to the genetic basis of disease, to ethical questions about genetic privacy.

If cow B is a clone of cow A and they bred with the same bull would their offspring's DNA be identical? Would all the offspring look alike?

Carla Easter, Ph.D.: Wow! Fascinating question. We cannot control for how the genes may rearrange. I would venture to say that the chances are pretty good that the offspring from Cow A and Cow B would be no more identical then the offspring of female twins who happen to have children by the same male. |
