Studies on the SAL locus in Drosophila pseudoobscura. I. The banding pattern of the tip of salivary chromosome 3 in larvae homozygous and heterozygous for SAL.
In the mutant sal the banding pattern at the tip of chromosome 3 is changed. Certain bands are compacted instead of being partially puffed. In sal(+)/sal heterozygotes, when the chromosome tips are paired they both show the sal(+) pattern or are intermediate; but when unpaired, each shows the pattern characteristic of its own genotype.
