Answer 4

You just carry in the letters into each box just like this so we get Yy for the top left box

Answer 5

Remember the big Y is for Yellow and is dominant

the little y is for green

so if you have YY, you will have a yellow plant
if you have yy, you will have a green plant
but when you have Yy, you will have a yellow plant because the big Y (for yellow) is dominant over the little y
