The domestic dog represents one of the most dramatic long-term evolutionary experiments
undertaken by humans. From a large wolf-like progenitor, unparalleled diversity in …

The dog is a unique species due to its wide variation among breeds in terms of size,
morphology, behaviour and lifespan, coupled with a genetic structure that facilitates the …

Hybridization is a natural or anthropogenic process that can deeply affect the genetic make-

The honeybee (Apis mellifera) has been threatened by multiple factors including pests and
pathogens, pesticides and loss of locally adapted gene complexes due to replacement and …

The dwarf phenotype characterizes the smallest of rabbit breeds and is governed largely by
the effects of a single dwarfing allele with an incompletely dominant effect on growth. Dwarf …

Sex-linked barring is a fascinating plumage pattern in chickens recently shown to be
associated with two non-coding and two missense mutations affecting the ARF transcript at …

Despite long‐standing interest in the evolution and maintenance of discrete phenotypic
polymorphisms, the molecular genetic basis of such polymorphism in the wild is largely …

Background Long-term selection experiments provide a powerful approach to gain empirical
insights into adaptation, allowing researchers to uncover the targets of selection and infer …
