When it comes to flies sometimes its hard to tell wether it's male or female. Researchers at the Janelia Farm Research Campus of the Howard Hughes Medical Institute did a study on how to tell the gender of the fly. They found that most cells in the flies are identical in both male and female.They say the reason is the influence of sex-determining genes is restricted to certain tissues. In the 1980s, it was known that a cascade of genes determines how tissues and organs develop in a sex-specific manner not just one. In female flies express one form of doublesex, and males another.Baker's group found that during fly development, doublesex switches on and off at different times and in different tissues.Baker's group found that during fly development, doublesex switches on and off at different times and in different tissues.
Well I don't quite understand the double-sex thing. I have always wondered about how to tell if a fly is a boy or girl. This was kind of a weird article and I just thought it would be funny to read but it's confusing to me. I guess it's pretty cool that a fly could be male or female i just know i wouldn't want to be both! I like who I am!
