In order to understand the basics of how sex cells develop, classic lab animals, like mice and fruit flies are of no use. That's why a team at the University of Illinois focused on simpler creatures: planarians, a type of flatworms, as ideal models for the study of germ cells that develop in eggs and sperm in th... |
