Captive breeding of wild animals is a first step of domestication. The process is accompanied by a number of adaptations to captive conditions, which resulting in behaviour, physiological and morphological changes. One of morphological consequences of domestication is a coat-colour mutation named Star (S) that is characterised by some unpigmented areas on the skin. The dominant mutation was first revealed in farm-bred populations of silver foxes, but the highest frequency of t...

Chemosensory cues from receptive females produce the activation of the pituitary–testicular axis and facilitate a complex display of sexual behavior in male mice. Testosterone output in response to a receptive female and the pattern of sexual behaviour were investigated in male mice (n=190) of three inbred strains BALB/cLac, CBA/Lac and PT at puberty (45 days of age) and in adulthood (90 days). Sexually naive pubertal or adult male was exposed for 10 min to a recep...
