Molecular Genetics of Coat Colour in Pigs
1 Dipartimento di Scienze e Tecnologie Agro-alimentari, Università di Bologna, Bologna, Italy. Correspondence to: [email protected], [email protected] AbStrAct Coat colour in Sus scrofa has been the matter of pioneering genetics studies carried out at the beginning of the last century. Since then, classical genetics studies have assumed that several loci affect this trait in pigs. W...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
A localized negative genetic correlation constrains microevolution of coat color in wild sheep.
The evolutionary changes that occur over a small number of generations in natural populations often run counter to what is expected on the basis of the heritability of traits and the selective forces acting upon them. In Soay sheep, dark coat color is associated with large size, which is heritable and positively correlated with fitness, yet the frequency of dark sheep has decreased. This unexpe...

may be important locally, but they do not represent a dominant global pattern. Additionally, we have not evaluated the possible effects of 3D slab morphology on trench-parallel flow in the wedge (e.g., 26) or beneath the slab (14, 27). Such flow is likely important locally andmay serve to strengthen or otherwise modulate the trench-parallel flow induced by trench migration. Our model essentiall...
