Horses and donkeys are different species, with different numbers of chromosomes. Of the two F1 hybrids between these two species, a mule is easier to obtain than a hinny, which is the product of a female donkey (jenny) and a male horse (stallion).The size of a mule and work to which it is put depend largely on the breeding of the mule's dam (female parent). male mule is properly called a horse mule, though often called a john mule. A female mule is properly called a mare mule, though often called a Molly mule. A young male mule is called a mule colt, and a young female is called a mule filly.
A fungal infection is at the root of toenails turning yellow. This infection is called onychomycosis, which generally starts at a nail's corner and spreads across the cuticle. It affects two toes most often: the big toe and the pinky toe.
Yellow toenails are usually a sign of trouble to come. Although harmless bacterial colonization can cause a color change in nails (usually green), and there is a rare condition called yellow nail syndrome, by far the most common cause of yellowish or brownish discoloration in the toenails is fungus infection.nce you know for sure that fungus is the reason for yellow toenails in your case, don't delay treatment. Infections are more easily treated if they do not involve the lunula (the whitish crescent shaped area near the cuticle). You will have to decide between various types of treatment for yellow toenails.
