[3pts] 2B.Coco is your favorite Koala bear, and she eats 370 g gum tree leaves per day on average. What do youexpect her breeding value to be? [3pts] C.If Coco mates with a male whose breeding value is +5 g, and they produce many progeny. what do youexpect the mean breeding value of their progeny to be?
