NABOURS'S GRASSHOPPERS, MULTIPLE ALLELO- 

 MORPHISM, LINKAGE AND MISLEADING 

 TERMINOLOGIES IN GENETICS 



In a review of Nabours's breeding experiments with grass- 

 hoppers, 1 Mr. Dexter makes a distinction between an interpreta- 

 tion of Nabours's and his own, where I fail to see a difference ex- 

 cept in terminology. This is so typical of much recent Mendelian 

 work that I am tempted to call attention to it. 



Nabours describes a cross between a female with characters BI 

 and a male with characters CE and comments on the production 

 of an individual with characters BEI. He says, as quoted, that 

 the "female parent gave at least one gamete containing the fac- 

 tors for the patterns of both her parents (B and /) and that this 

 double character gamete was fertilized by one of the E gametes 



Dexter prefers to call the supposed exceptional BI gamete of 

 Nabours Bcel, and the supposed E sperm which fertilized it bcEi, 



tations ? Is it anything but verbal ? Is there anything significant 

 in the small letters which Dexter has added to Nabours's form- 

 ula?? If go, what is their significance? Do they mean any more 

 than the extra zeros in the expression 1.000 as compared with 1.0? 



peated. "If then BEI forms should app.-.-ir a-am and in these 

 when mated to other forms the factors B and / should be found 

 to stay together to the same extent as they before separated, it
