Answer:

9 out of 16 (also 9/16)

Explanation:

Count the likeliness of the offspring to be round:

RR, Rr, rR, rr

round shape is 3 out of 4 times

Count the likeliness of the offspring to be yellow:

YY, Yy, yY, yy

yellow color is 3 out of 4 times

Multiply the likeliness of being round and being yellow (since they are two independent probabilities, we are using multiplication rule):

3/4 * 3/4 = 9/16

Make me the brainliest ;)
