Yes, hemophilia is an autosomal recessive disorder. Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern.emale chromosome has another X-chromosome, which is dominant and masks the defective gene, and it is quite rare that both â¦ the chromosomes have recessive alleles. But, in males, the Y-chromosome has nothing to over mask the defective gene and the abnormality shows up in the form of the disease.
A papilloma virus (wart) is probably what causes horse sarcoids. A high proportion of sarcoids contain genetic material that is identical, or very closely related, to the bovine papilloma virus (BPV).sually the clinical appearance is adequate to make a diagnosis. Especially if several sarcoids of more than one type are present on the same horse. It is more difficult if only one occult sarcoid is present.
Most of us know that horses can suffer from equine gastric ulcers syndrome (EGUS), a condition where horses develop ulcers in their stomachs. Horses can also develop ulcers in their large intestines. This condition is referred to as colonic ulcers or right dorsal colitis (RDC). In a recent study of 545 horses tested for RDC, 44% of nonperformance horses and 65% of performance horses had colonic ulcers. Although they are not as prevalent as gastric ulcers, colonic ulcers are still a significant problem, especially in performance horses. RDC seems to be closely associated with stress.
