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.
Sometimes, thick yellow toenails indicate that you may have a hard-to-diagnose foot condition. In some cases, your podiatrist might take a biopsy of the alleged fungus and have it analyzed by a pathologist.
