Carol Blair 25th April 2017 18:51 What was the answer to #7? Admin Davy Falkner 15th May 2017 11:24 Hi Carol, the quiz has now been updated so that the correct answer to question #7 is given. TGR 26th May 2017 07:41 #14 “mtDNA is only passed from the mother to the child, because only eggs have mitochondria” – this statement is inherentely wrong, as also the sperm has mitochondria (otherwise, the energy for the movement would be missing). However, as it is correctly stated in the linked NYT article, these mitochondria are fastly depleted after the sperm-oocyte-Membrane fusion, and are normally no longer detectable in the Zygote. Therefore, I consider to reformulate the question or Change the correct answer Option. Admin Davy Falkner 6th June 2017 17:00 Thank you for brining this error to our attention. The question has been corrected. Comments are closed.
