Question

Construct the cross between RrYY and RrYY

Answer 1

Parents: RrYY (Round and Yellow) × RrYY (Round and Yellow)

Gametes: RY and rY RY and rY

F1:

	RY	rY
RY	RRYY ​(Round and Yellow)	RrYY ​(Round and Yellow)
rY	RrYY ​​(Round and Yellow)	rrYY ​​(Wrinkled and Yellow)

So, 75% of the F1 generation would have round and yellow seeds while 25% will have wrinkled and yellow seeds.
