The narrow-sense heritability (hn2) for potato weight in a starting population of potato plants is 0.42, and the mean weight is 1.4 pounds. if a breeder crossed plants with average potato weights of 1.9 and 2.1 pounds, respectively, what is the predicted average weight of potatoes from the offspring
