brown gene | dilute gene

Test Gene Description
The brown gene controls the synthesis of eumelanin. Mutations in the brown gene may change the content of eumelanin and thus affect the appearance of coat color. Two mutation sites have been found on the brown gene to affect the appearance of coat color. The allele b corresponds to chocolate color , and the allele bl corresponds to cinnamon, the inheritance pattern is basically recessive, but B is dominant relative to b and b is dominant relative to bl (B > b > bl), so as long as there is one allele that is B coat color would be black, but with one allele b and one bl, it would be chocolate.

The dilution gene is related to the transport of melanin bodies, so when the dilution gene mutations may cause the melanosomes to not be transported to their destinations correctly, resulting in uneven distribution of pigment in the hair, a mutation site has been found in the dilution gene that leads to lighter hair color , the genetic mode is recessive inheritance, that is, two alleles d at the same time will have the performance of dilution.
