L=4080 angtron\(\Rightarrow\)N=4080 x 2 / 3,4=2400
-So Nu tung loai cua gen troi
2A+2G=2400(1) ; 7A-9G=0(2) tu (1) va (2) ta co
A=T=675 ; G=X=525
-So nu tung loai cua gen lan
2T+2X=2400(3) ; 3T-13X=0(4) tu (3)va(4) ta co
A=T=975 ; G=X=225
a)So luong tung loai Nu o F1 la
A=T=675+975=1650 ; G=X=525+225=750
b)So luong tung loai Nu cua moi loai hop tu o F2 la
