Variance Standard Deviation
Covariance Correlation coefficient
Regression line y = a + bx
Phenotypic variance
VP = VG + VE + VGE, but VG = VA + VD + VI, so VP = VA + VD + VI + VE + VGE
Broad-‐sense heritability Narrow-‐sense heritability
Response to selection R = h2 x S where S is the selection differential
Allelic frequencies p + q = 1
Hardy-‐Weinberg p2 + 2pq + q2 = 1
Inbreeding
F(AA) = p2 + Fpq f(Aa) = 2pq – 2Fpq f(aa) = q2 + Fpq
Mutation
Variance in allelic frequency due to genetic drift
