Race condition
A race condition or race hazard is the behavior of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.
Timbavati Game Reserve
Lions with a recessive gene causing the coats to be snow white (though not albino) reappeared in the Timbavati in 2006 after an absence of many years. Their white coats are not the product of albinism, a relatively common condition resulting from a failure to develop pigment, but from another condition called "leucism," in which the pelt is white but eyes and skin are pigmented. The condition is rare and also termed a "chinchilla mutation." It is thought to represent an evolutionary stage in the progressive loss of pigmentation. The white mutation, which affects two of the pigments involved in coat coloration, is expressed only when two conditions pertain:
(1) Both parents carry the recessive "white gene";
(2) the offspring inherit the recessive gene of each parent. If a cub receives a dominant "tawny" gene from either parent, its pelt will
be tawny. Thus a litter may contain both tawny and white cubs.
