Effect of DGAT1 gene polymorphisms in coarse-haired fat-tailed lambs of different genotypes [PDF]
The aim of this study was to investigate the DGAT1 gene polymorphism and its effects on lamb weight in kazakh and tajik sheep breeds. A total of 97 blood samples were collected from purebred (еdilbay х еdilbay) and crossbred lambs (еdilbay x gissar ...

The nature of the purebred-crossbred genetic covariance
SUMMARYEpistatic models are examined for conditions which result in a negative covariance between a sire's purebred and test-cross progenies. It is found that heterozygote superiority is not a necessary condition for its occurrence. The frequencies of the same allele in the selected population and in the tester should be divergent.

THE COURSE OF CARDIOMYOPATHY IN PUREBRED CALLAMUSES
The heart belongs to the order of the organ, which participates in the movement of blood circulation and lymph in the body, manifests itself in an empty muscle organ. The heart of mammals: the base and upper part, the left and right surface, the front and the middle edge are separated into parts.

Background Demand for intentional crosses of purebred dog breeds, often labelled ‘designer crossbreeds’ (e.g., Labrador Retriever X Poodle, the ‘Labradoodle’), has recently increased in the UK. This study aimed to explore this phenomenon by comparing pre-

THE EVALUATION OF IRAQI PUREBRED ARAB HORSES OVER 12 YEARS
Changes in the exterior purebred Arab horses during the last 12 years have been analyzed. Measurements with regard to the exterior were made on the presently living 238 horses from Baghdad, Nenava and Dialla.

Recently, an important element in improving the genetic traits of dairy cattle on commercial farms is the use of interbreeding (crossbreeding). The use of crossbreeding makes it possible to use a variety of additive genetic levels between breeds to grow ...

Booming UK ownership of designer-crossbreed dogs resulting from intentional crossing of distinct purebred breeds is often motivated by perceived enhanced health, despite limited evidence supporting a strong ’hybrid vigour’ effect in dogs.

Simple Summary The welfare of purebred dogs and cats is being undermined by fashion trends that popularize extreme shapes. Official descriptions of breeds require their distinctive characteristics to be compatible with good health. Nevertheless, extremes
