Funky chickens have sexual-identity issues
Some chickens have sexual-identity issues, waddling around with half-male and half-female plumage.
Now researchers have figured out the cause of the gender-confusing traits: Half of their bodies are full of female sex cells, while the other half contains mostly male cells.
“This research has completely overturned what we previously thought about how sexual characteristics were determined in birds,” stated study researcher Michael Clinton of the University of Edinburgh, Roslin, in Scotland.
