Piebald Camels
Animal breeds are the diverse outcome of the thousands-year-long process of livestock domestication. Many of these breeds are piebald, resulting from the artificial selection by pastoralists of animals bearing a genetic condition known as leucism, and selected for their productive, behavioural, or aesthetical traits. Piebald dromedary camels have not been studied or discussed before, and their ...
متن کاملHomozygosity in piebald trait.
A severely affected child born to consanguineous parents is interpreted as being a homozygote for the dominantly inherited piebald trait. The striking phenotypic difference between the parents and the child implies intermediate inheritance of this condition, and the family also illustrates that consanguinity should not always be taken to indicate genetic heterogeneity and recessive inheritance.
متن کاملPiebald mutation on a C57BL/6J background
The classic piebald mutation in the endothelin receptor type B (Ednrb) gene was found on rolling Nagoya genetic background (PROD-s/s) mice with white coat spotting. To examine whether genetic background influenced the phenotype in the piebald mutant mice, we generated a congenic strain (B6.PROD-s/s), produced by repeated backcrosses to the C57BL/6J (B6) strain. Although B6.PROD-s/s mice showed ...
متن کاملSymplectic Camels and Uncertainty Analysis
Gromov’s non-squeezing theorem is a relatively new results in symplectic topology that provides a non-trivial constraint on the propagation of uncertainty in a Hamiltonian system. While the application to nonlinear systems is difficult, one can apply the theorem to obtain bounds on the propagation of uncertainty in the linearized system, by exploiting the fact that the flow of the linearization...
متن کاملReproduction in Old World camels.
The article reviews aspects of the basic reproductive biology of the camel, such as puberty, breeding season, ovarian dynamics, synchronisation of ovarian activity and artificial insemination, and superovulation and embryo transfer. Pregnancy and parturition are also discussed.
