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
