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

摘要

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.
