Nothing. A stallion is an ungelded male horse and a jack is a male donkey. Only females and males can breed together and produce offspring.
Stallions and jacks are both male.

Jack Cross has written: 'Cricket' -- subject(s): Cricket
A cross between a jenny (female donkey) and a stallion (male horse) produces a mule, which is a hybrid animal. Mules are known for their strength, intelligence, and surefootedness, making them valued for various tasks such as trail riding and pack animals.
The process is no different from a stallion mating with a mare or a jack mating with a jenny. Stallion mounts the jenny, inserts his penis in the jenny's vagina, ejaculates and dismounts.
A hinny is not a horse, wild or otherwise. A hinny is the offspring of a horse stallion and a donkey jenny. Hinnys, unlike mules, are quite rare as the embryos produced through this mating are less viable than the donkey jack, mare cross.
