![]() ![]() Originally, pig (Sus scrofa) has emerged in the South East Asia during the early Pliocene (~5.3–3.5 Myr ago) and then spread across most of the Eurasian continent. Much has been argued on whether pig was domesticated independently across multiple locations or it was adopted by humans only once and then transported elsewhere. Pig domestication has started over 10 000 years ago and has had important consequences on human life, changing our agricultural and medical practices. Closer inspection reveals multiple pigmentation traits and pattern that differ between the light and the dark morph to compose complex coloration … Read More As they expected, statistical test reveals that the dark models are significantly more attacked than light models. First of all, they implemented an experimentation with plasticine models to count the number of attacks on each coloration morph. This study is composed of two main parts : first to understand and to evaluate the complexity of coloration phenotype and then to find the mutations responsible of those variation in traits and on which morph selection is acting on. Adaptation for crypsis is the strongest hypothesis to explain prevalence of the light morph compared to the black morph, and they wanted to dissect the genetic basis of this adaptation. are interested in coloration of the deer mice (Peromyscus maniculatus) present on the light-colored soils of the Nebraska Sand Hills. But dissection of those genes or loci are rarely studied, and it remains unclear which of single pleiotropic mutations or multiple mutations with independent effects are responsible to elaborate complex phenotypes. Pleiotropy of genes is often the main solution to explain genetic basis of complex phenotypes (i.e., those composed of multiple traits). ![]()
