If you don't like those genes, then open up expansionsetup.gd with any decent text editor and use a Find utility to locate 'Emily' or any other unique name. You can change the genes to whatever you want, change the condition after the "if" to false, or delete their entire section starting at the "if" or "elif" to the last line with one more leading tab than the start. Note there are two sets of code, the first is for playing without Ralph's tweaks and the second is for playing with Ralph's tweaks.
