MadSci Network: Genetics |
in preparation for answering this question i read both the article in discover and the press releases from the scientists who performed the experiments. Acording to their results the clones were identical, all of the mice were coffee-colored. this was confirmed in the third experiment they conducted. As for you question on whether or not there can be changes among dominant and recesive genes the answer is no for this method. In order for there to be a difference there would have to be foreign dna introduced into the embryos. In there experiments it was all the same, just from one parent. they tested this in an interesting way. they took oocytes from mice which are black in color, took out the nuclei, and put in the nuclei of a mouse that is coffee colored. since all of the offspring were coffee colored they determined that the offspring were actual clones of the original. which, if its a clone, there is no difference.
