Gay Fruit Flies

Scientist in the Univerity of Chicago have discovered that if you turn off this one particular gene in the fruit fly, then the gene for same-sex attraction turns on.

When placed in a container with female and male flies the “gay” flies spent 10x more time chasing after the male flies than female. Wow talk about male attractions. The scientist says the “straight” gene developed about 2 million years ago was so that the male flies didn’t spend so much time chasing the males.

Did i mention that this “gay” “straight” gene only exists in these fruit flies?
