The characteristics of several mutants of Drosophila melanogaster and Drosophila simulans lacking particular salivary gland chromosome puffs are described. On the basis of their observed behaviour in heterozygotes these puff mutants can be classified into puff structural gene and puff regulating gene mutants. Other types of mutation affecting the larval and prepupal puffing cycle include lethals, mutants controlling puff size, and chromosome aberrations which divide a puff into two separate puffs.
