The interplay between these two genes determines the colour of a Labrador Retriever, and is widely used as an example of epistasis. If a dog possesses the dominant phenotype for the extension allele (genotype EE or Ee), then it will display the fur colouration determined by its brown locus genotype, while a dog with the recessive extension ...
The dilute gene d is recessive to the wild type allele D. A gene test can be used to determine a dog's genotype concerning genes for pigmentation. In some dog breeds lightened by the dilute gene, the mutation d is associated with color dilution alopecia (CDA). Since not all breeds in which the gene occurs exhibit these problems, it is suspected ...
Research indicates that the majority of variation in coat growth pattern, length and curl can be attributed to mutations in four genes, the R-spondin-2 gene or RSPO2, the fibroblast growth factor-5 gene or FGF5, the keratin-71 gene or KRT71 [15] and the melanocortin 5 receptor gene (MC5R). The wild-type coat in dogs is short, double and straight.
Gene therapy was to restore some of the sight of mice with achromatopsia. The results were positive for 80% of the mice treated. [7] In 2010, gene therapy for a form of achromatopsia was performed in dogs. Cone function and day vision have been restored for at least 33 months in two young dogs with achromatopsia.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
"Gene therapy has emerged as a new modality that could interfere or modify the expression of several proteins, thus it could alter the pathologic remodeling of the heart muscle that exists in ...

In dogs, the Liver color is caused by dilution of the eumelanin (black) pigment by the B locus. The gene that causes Liver is recessive, so a BB or Bb dog has normal black pigment. Only a bb dog is Liver. There are several different recessive b genes, but they all turn the coat brown. They are only distinguishable through genetic testing. [2]
