Candidate genes for shell colour polymorphism in Cepaea nemoralis
The characteristic ground colour and banding patterns on shells of the land snail Cepaea nemoralis form a classic study system for genetics and adaptation as it varies widely between individuals. We use RNAseq analysis to identify candidate genes underlying this polymorphism. We sequenced cDNA from the foot and the mantle (the shell-producing tissue) of four individuals of two phenotypes and pr...
متن کاملRAD-Seq derived markers flank the shell colour and banding loci of the Cepaea nemoralis supergene
Studies on the classic shell colour and banding polymorphism of the land snail Cepaea played a crucial role in establishing the importance of natural selection in maintaining morphological variation. Cepaea is also a pre-eminent model for ecological genetics because the outward colour and banding phenotype is entirely genetically determined, primarily by a 'supergene' of at least five loci. Unf...
متن کاملThe inheritance of some characters in Cepaea hortensis and Cepaea nemoralis (Gastropoda).
N recent years the remarkable polymorphism of snails of the genus Cepaea IHeld has continued to attract considerable attention. The variation from place to place in the proportions of the different phenotypes has proved to be useful material for the study of evolution in natural populations (CAIN and SHEPPARD 1950, 1954; CLARKE 1960; CLARKE and MURRAY 1962; LAMOTTE 1951, 1959; SCHNETTER 195 1 ;...
متن کاملInterference coloration as an anti-predator defence.
Interference coloration, in which the perceived colour varies predictably with the angle of illumination or observation, is extremely widespread across animal groups. However, despite considerable advances in our understanding of the mechanistic basis of interference coloration in animals, we still have a poor understanding of its function. Here, I show, using avian predators hunting dynamic vi...
متن کاملAnti-predator defence drives parallel morphological evolution in flea beetles.
Complex morphological or functional traits are frequently considered evolutionarily unique and hence useful for taxonomic classification. Flea beetles (Alticinae) are characterized by an extraordinary jumping apparatus in the usually greatly expanded femur of their hind legs that separates them from the related Galerucinae. Here, we examine the evolution of this trait using phylogenetic analysi...
