REGULAR MENDELIAN INHERITANCE 



19-6 



Table 19-3 describes 8 asci dissected from a hybrid heterozy- 

 gous for mating type, galactose fermentation, maltose fermenta- 

 tion, and a pair of genes affecting the ability of the organism to 

 grow in Burkholder's medium without added pantothenate. The 

 - and + signs under the columns G and MA indicate whether or 

 not the organism produced gas in a medium containing galactose 

 of maltose respectively. The figures under the column PAN show 

 the turbidity reading registered in a Klett Photoelectric Colori- 

 meter, after four days in a culture tube of Burkholder's medium 

 without added pantothenate.
