Answer 1

I think for the first square its RR, second square Rr, third square Rr, and the fourth square rr. Usually they use uppercase for the dominant trait and lowercase for recessive so Im assuming number one would be abount 75%? the second one probably around 25% ns tho, Idk the last one But i hope this helps you, have a wonderul day/evening. :)
