N (s) = 2^3 = 8 (2a 1g ) = (aag) , (aga) , (gaa) n(2a1g) = 3
frekuensi harapan 2a1g = 3/8 x 40 = 15 kali

whongaliemn (s) = 2 x 2 x 2 = 8 (2 A , 1G) = (A ,A ,G) (A , G ,A) (G ,A, A) n (2A ,1G) = 3 P (2A ,1G) = n (2A ,1G) / n (S) = 3/8 fh (2A , 1G) = P (2A , 1G) x n (percobaan) = 3/8 x 40 = 15
(2a 1g ) = (aag) , (aga) , (gaa)
n(2a1g) = 3
frekuensi harapan 2a1g = 3/8 x 40
= 15 kali
= 8
(2 A , 1G) = (A ,A ,G) (A , G ,A) (G ,A, A)
n (2A ,1G) = 3
P (2A ,1G) = n (2A ,1G) / n (S)
= 3/8
fh (2A , 1G) = P (2A , 1G) x n (percobaan)
= 3/8 x 40
= 15
