Full transparency and accessibility of the embryos are some of the advantages which recently made fish a valuable model organism for vertebrate development. The Bernese Mountain dog is a very popular breed. Nevertheless, the population is burdened with some genetic diseases. In a population genetic study we investigated the prevalence and heritability of the diseases to enable a breed specific breeding strategy. The ophtalmoscopic picture shows simple retinal folds in the tapetal fundus.
Affected dogs have no impaired vision.
Because of their small size and friendly character, beagles are popular companion dogs and the favorite laboratory dogs in medical research. Labrador Retriever Labrador Retriever are used as gun dogs as well as as pets. To help the breeders in producing healthy dogs, a study is conducted to find out prevalence and heritability of important diseases in the Labrador population and to define an effective breeding strategy to avoid genetic diseases in this breed. The choice of a puppy from a litter is a far-reaching decision for the dog keeper. The new companion for the next ten years should be healthy, free of genetic diseases, friendly and bearer of all the desired characteristics which are specific for the breed.
