Epistasis, phenotypic disequilibrium and contrasting associations with climate in the land snail Theba pisana.

Heredity - 1 Mar 2012

Johnson M S

Abstract excerpt

Hotter conditions favour effectively unbanded (EUB) shells in the snail Theba pisana. T. pisana is also polymorphic for colour of the shell's apex, determined by a pair of alleles at a locus linked to the banding locus. Apex colour is epistatic to shell banding, such that banded snails with a dark apex have darker bands. Annual censuses over 22 years across an ecotone between a sheltered Acacia thicket and open...
