Pls help!! Just give me the answers to the top part and the boxes

50% offspring will be RR

Step-by-step explanation:

I set up my table and solved it I can teach you if you would like

1/4 because there is 4 grades.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
