“Gynandromorph: Noun: An abnormal individual, esp. an insect, having some male and some female characteristics.”
While setting up several hundred crosses over the past few days, I saw thousands of flies. One of them in particular caught my eye:
This fly clearly has sex combs on both forelegs, but the genitals look neither fully male nor female. The left side of the head is male, as the FM7 balancer gives a bar shaped eye if no wild-type chromosome is present. The right side of the head is likely female, but the visible phenotypes can’t determine this for certain. I’m not sure why the wing is messed up.
A thorough explanation of what’s actually happened to this unusual creature can be found here: http://amasianv.wordpress.com/2012/05/16/its-a-male-its-a-female-no-its-a-gynandromorph/
