FORMULAE 



Baur's plan of using non-significant letters has 

 no doubt certain advantages, but in practice signifi- 

 cant letters are too useful to be given up. We have 

 followed a plan which avoids the objections of the 

 presence and absence scheme, and has the advantage 

 of significant letters. In this plan a small letter is 

 used for the mutant factor if recessive, and a large
