Editor: Replace "Female" check box in BodyPart records with "Gender" combo box
Part 2/2 regarding the "Female" check box.
We currently use a "Female" check box to determine the gender a particular body part is linked to. This approach isn't very intuitive which is why we should replace the check box with a combo box ("Male", "Female"). This will also allow us to extend the list of gender types in the future.
