Two varieties of maize averaging 25 and 125 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 75 inches in height. Of the 500 F2 plants, the Shortest 2 is 25 inches and the tallest 2 are 125 inches. What will be number phenotype observe in F2 progeny and number of polygene contribute for that character respectively?
