Mimicry is an example of an adaptation that requires the integration of several components. Genetic characterisation of a mimicry polymorphism in a butterfly reveals the expected suppression of recombination among its components, preventing the production of unfit character combinations.
Heterostyly is a wide-spread floral adaptation to promote outbreeding, yet its genetic basis and evolutionary origin remain poorly understood. In Primula (primroses), heterostyly is controlled by the S-locus supergene that determines the reciprocal arrangement of reproductive organs and incompatibility between the two morphs. However, the identities of the component genes remain unknown. Here, ...

Freitas, Camilo Salazar, Karina Lucas Silva-Brandão, Tatiana Texeira Torres, Joron Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene fl...
Supergene mineral assemblages rich in Pb, As and P occur on the dumps after historical mining of base-metal deposit Kvasetice (Havlíčkův Brod ore district, Bohemian-Moravian Highlands, Czech Republic). The primary hydrothermal assemblage pyrite > sphalerite arsenopyrite galena >> boulangerite hosted quartz veins is partly different from other similar localities this area, which belong ...
Recent studies appear to overthrow the hypothesis that, in butterfly species exhibiting Batesian mimicry, a multi-gene complex or 'supergene' controls the multiple differences between mimetic and non-mimetic individuals, suggesting instead that near-perfect mimicry can be produced by a set of changes within a single locus, together with changes in the genetic background.
The induction of tissue formation, and the allied disciplines of tissue engineering and regenerative medicine, have flooded the twenty-first century tissue biology scenario and morphed into high expectations of a fulfilling regenerative dream of molecularly generated tissues and organs in assembling human tissue factories. The grand conceptualization of deploying soluble molecular signals, firs...
