If both parents are dominant, (could also make it like elder + Dom exclusive,) parents can see recessive stats of the egg. Similar to how Dom parents can see each other's recessive stats.

while this would be amazing addiction and i 100% like it, technically having both parents Dom already gives you ability to estimate stats of eggs with 100% accuracy
dom parents pass down the better of their stats 100% of the time
which means if one has A/D and the other is B/D, 50% of the babies will be A/B and the other B/A
same comes for D/B C/B where 100% of the kids would be B+/B (B + B passed down crits on dom stat and leaves same recc) <3
