The laboratory mouse is an artificial construct with a complex relationship to its natural
ancestors. In 2002, the mouse became the first mammalian model organism with a reference …

Meiotic drive occurs when one allele at a heterozygous site cheats its way into a
disproportionate share of functional gametes, violating Mendel's law of equal segregation …

Behavioural isolation may lead to complete speciation when partial postzygotic isolation
acts in the presence of divergent‐specific mate‐recognition systems. These conditions exist …

Multilocus hybrid zone (HZ) studies predate genomics by decades. The power of early
methods is becoming apparent and now large datasets are commonplace. Relating …

Hybrid sterility (HS) belongs to reproductive isolation barriers that safeguard the integrity of
species in statu nascendi. Although hybrid sterility occurs almost universally among animal …

The disruption of meiotic sex chromosome inactivation (MSCI) has been proposed to be a
major developmental mechanism underlying the rapid evolution of hybrid male sterility. We …

Abstract Background The Mus musculus musculus/M. m. domesticus contact zone in Europe
is characterised by sharp frequency discontinuities for sex chromosome markers at the …

The effects of gastrointestinal tract microbiota (GTM) on host physiology and health have
been the subject of considerable interest in recent years. While a variety of captive bred …

The Dobzhansky-Muller model of incompatibilities explains reproductive isolation between
species by incorrect epistatic interactions. Although the mechanisms of speciation are of …

The classical definition posits hybrid sterility as a phenomenon when two parental taxa each
of which is fertile produce a hybrid that is sterile. The first hybrid sterility gene in vertebrates …
