Population Genetics:
p + q = 1
P + H + Q = 1
p = P + .5H
q = Q + .5H
In equilibrium, P = p2, Q = q2 and H = 2pq
P1 = (1-s1)p2 ________
(1-s1)p2 + (1-s2)2pq + (1-s3)q2
Q1 = (1-s3)q2 ________
(1-s1)p2 + (1-s2)2pq + (1-s3)q2
H1 = (1-s2)2pq ________
(1-s1)p2 + (1-s2)2pq + (1-s3)q2
p1 = (1-s1)p2 + (1-s2)pq_______
(1-s1)p2 + (1-s2)2pq + (1-s3)q2
q1 = (1-s3)q2 + (1-s2)pq_______
(1-s1)p2 + (1-s2)2pq + (1-s3)q2
If Overdominance:
pE = s3/(s1+s3)
qE = s1/(s1+s3)
If fitness for the recessive is 0:
t = 1/qt – 1/q0
qt = q0/(1+tq0)
migration:
qnew = qA + m(qB-qA)
Statistics:
Variance = 2 = [(xi – x)2]/(n-1)
Standard deviation =
Covariance = COV = [(xi-x)(yi-y)]/(n-1)
Correlation rx,y = COVxy/(xy)
Regression by,x = COVxy/2x
Quantitative Genetics:
P = G + E
P = BV + GCV + Ep + Et
P = BV + GCV + Ep + Et
PA = BV + GCV + Ep
Prediction equation:
y = y + by,x(x – x)
