Isolation and evaluation of dextral-specific and dextral-enriched cDNA clones as candidates for the handedness-determining gene in a freshwater gastropod, Lymnaea stagnalis.

Abstract excerpt

The handedness of gastropods is genetically determined. The freshwater gastropod Lymnaea stagnalis is a normally dextral species, but contains minor sinistral populations. The gene responsible for handedness determination in this species is predicted to function maternally and specifically in the dextral-ovipositing snail. In this study, we used differential screening and cDNA subtraction to isolate eight...
