DISCUSSION AND CORRESPONDENCE 



SUBSTITUTES FOR THE WORDS HOMOZYGOUS

To THE Editor op Science : Those who have 

 attempted to explain the fundamentals of 

 genetics to live-stock breeders and to others 

 with a natural distaste for terminological 

 refinements are aware how ineffective some of 

 the available nomenclature is for this pur- 

 pose. A technical word to be successfully 

 applied to a new idea in a non-technical dis- 

 cussion must suggest its meaning readily, 

 must be free from misleading connotations 

 and should be sufficiently novel so that the 

 point will not be missed by the audience 

 owing to a spurious aspect of familiarity. 

 That the words homozygous and heterozygous 

 are admittedly defective on the first count is 

 shown by the number of evasions to be found 

 in the literatiu-e, but it has not been generally 

 recognized that all their substitutes in common 

 use fail in the other two particulars. To prove
