Please Be Carefull !!

As I see it there are two reasons for a second proof. The first is just in case of human misinterpretation of what one is seeing in the analysis particularly in the (unlikely) event that an Even-More-Recessive thing is lurking that just mucks up what one is seeing.

The other - and it is to the credit of the community that this hasn't happened - is for evidence to be falsely photoshopped of some new trait or other for the lolz: "OH HEY, I'VE DISCOVERED THE WHIRLY-TWIRLY TAIL. AND IT'S SUPER-RECESSIVE." Like that.

It would be a short-lived prank to be sure, but it could happen.
