#Repost @biology_beth (@get_repost) ・・・ πŸ‘©πŸΌβ€πŸ”¬WOMAN CRUSH WEDNESDAY πŸ‘©πŸΌβ€πŸ”¬ Nettie Stevens was born in 1861. People thought that the gender of your baby was controlled by temperature (like reptiles) and what was eaten during pregnancy. Nettie studied bugs and used them to discover that sperm cells contain X and Y genes, which determine gender. Edmund Wilson made the same discovery around the same time. Nettie published her work first and with more evidence than him but, he was given the Nobel prize. He did credit her work in his papers though! #biology #biologyteacher #womancrushwednesday #nettiestevens #xy β€’ β€’ β€’ #bio #biology #biologymajor #biologyteacher #teacher #teachers #teaching #womeninstemwednesday #women #history #stem #science #learning
