Liane Russell dating history

Details

Liane Brauch "Lee" Russell (August 27, 1923 – July 20, 2019) was an Austrian-born American geneticist and conservationist. Her studies in mammalian genetics provided the basis for understanding the chromosomic basis for sex determination in mammals and the effects occasioned by radiation, drugs, fuels and waste on mice. Her research allowed better understanding of genetic processes in mammals, mutagenesis and teratogenesis effects on mammals, and knowledge of how these processes can be prevented and avoided. She determined that developing embryos were most vulnerable to the effects of radiation during the first seven weeks of pregnancy and therefore recommended that non-urgent diagnostic X-rays be taken in the 14 days after the onset of a woman's menstrual period, a standard that became internationally accepted in radiological practice. She was also the first to discover that the Y chromosome determines maleness in mammals.
