Abstract excerpt

The present study extends evidence that Drosophila heat-shock genes are distinctively evolvable because of insertion of transposable elements by examining the genotypic diversity and phenotypic consequences of naturally occurring P element insertions in the proximal promoter regions of two small heat-shock genes. Detailed scrutiny of two populations revealed 16 distinctive P transposable elements collectively...
