An increased knowledge base and understanding of the factors both genetic and environmental that put an english bull dog at risk should help veterinarians to identify the deseases of the english bull dog breed and prepare veterinary prevention programs. The Genetic predisposition of the english bull dogs is the inherited risk or genetic susceptibility of developing a illness or an abnormal condition. The English bulldog who has a genetic risk for a disease does not mean will get that disease, but the risk for of the english bull dogs may be higher respect to the general population of Dogs. The Englisg Bull dogs have a greater genetic likelihood of developing certain characteristics or conditions for example respect to dysplasia, brachycefalic sindrome, eye's problems, skin deseases or genetic tendencies toward obesity.
An english bull dog could have a genetic predisposition, but not demonstrate this trait unless environmental conditions, because the english bull dogs predisposition could be overcome by protective evironmental circustances. But many negative genetic effects which influences the phernotype of the english bull dogs can be modified by the environmental conditions, for example the joint deseases as dysplasia.So before to buy english bull dogs is good to know the parents of the buldog pupy because the family history is a well documented risk factor to developing illnesses in the descendents. Researchers find out that genes functions of many deseases is developing in a complex environment. The Environmental factors and the genetic predisposition of English bull dogs contribute to the phenotipe observed in condition disorders as joint problems.The Environmental factors as the slidey floors could contribute for the onset and exacerbation of these problems. Many english bull dogs are suffering of skin deseases this could be a breed genetic predisposition to skin problems toghether with an hypersensitivity to environmental factors.
The english bull dog's DNA is packaged in compact units named cromosomes. An alele gene is a paired gene whose genetic difference from a correct gene could be responsible of disturbs. The genetic predisposition of the english bull dogs is the latent susceptibility to suffer problems that could be activated under a certain condition. A genetic predisposition is the genetic efect that influences the dominant and recessive phenotipe of the english bull dogs but which can be modified by the evironmental conditions. The phenotype of an english bull dog is his physical appearance and constitution or a specific manifestation of somatic traits, such as body size or eye's color. Phenotipe is determined by genotipe, or by the identity of the alleles at one or more positions on the chromosomes. A dominant alele refers to a genetic feature that supreses the recesive alele. Also if the interaction of genees and evironment usually means contexts of a negativ trait, the impact of their interaction can be different sometime armful, sometime neutral or sometime protective. Another example of the interaction between genotipe, evironment and random variations are the englisg bull dog's infections of the ear. The infection should develop because of a genetic predisposition of english bull dogs that help the overpopulation of yeast or bacterial but the evironmental factor to clean often the ears could evite the demonstration of syntoms.
The phenotipe of an english bull dogs is the detectable structural, biocemical, phisiological and beavioral characteristic of an english bull dog and is determined by an interaction between genotype environment. Some genetic efects in english bull dogs may be seen only under certain environmental condition, because the genetic code predisposes to be susceptible. The starting point of the studies over genetics were the researches of Gregor Mendel published in 1865 and 1866, while the Drosophila melanogaster is the most valuable organisms used in biological research, in genetics and developmental biology.A Classic Example of English bull dogs Inherited Predisposition is Demodex. Veterinarians say that Demodectic Mange is a type of mange can only be contracted from the mother during whelping. Demodex Desease can appear in localized demodicosis or generalized demodex in which several places of the coat get this condition. Generalized demodectic should be an inherited condition for a deficiency of a specific type of T-cell. The Demodex Mite is present in most dogs but without demonstrate signs of deseases. The hereditary component in this case is the susceptibility to hairloss and secondary skin infections as a result of overgrowth of the mite population. Any condition causing sufficient immunosuppression can lead to problems with demodicosis. When the english bull dog is not treated and resolves on its own, that is a good sign that an inherited immunodeficiency is not present. The dog breeds with tendency to develop demodecosis include shar pei, West Highland white terrier, Scottish terrier, English bulldog, Boston terrier, great Dane, Weimaraner, Airedale, Malamute and Afghan.
