this is a screen shot of of my king's cubs, he have some cubs with mutation, but one can't spot them right away because whether or not the cub has mutation, it will always say something in the text box instead of a blank text box for a non-mutated cub.
I think if we remove the 'none' text, leave the boxes of non-mutated cubs blank, it can be way more easier to see how many mutated cub a king has, or how many a lioness has.

everyone's suggestions:
replace none with an 'X'.
let mutations to have a different text color from none mutated.
have a drop down bar to let us chose 'show all' or 'show mutated'
