Most fox odor is hereditary, but not necessarily all of it is inherited. First of all, fox odor caused by abnormal secretion of sweat glands is a hereditary disease, it is autosomal dominant, once the parents have fox odor, the children are likely to be inherited. The probability of inheritance is related to the genes carried by the parents, for example, only the father carries the gene of fox odor, but the mother does not, the chance of inheritance is 50%, and at the same time, there is a 50% chance that it will not be inherited, so fox odor is not necessarily inherited to children. There is another kind of fox odor due to local bacterial infection, the main reason for this kind of fox odor is the odor caused by the bacterial decomposition of sweat, through active anti-infection treatment fox odor can be eliminated, this type of fox odor will not be inherited.
