Parity \Par"i*ty\, n. [L. paritas fr par, paris, equal: cf F.
parit['e]. See {Pair}, {Peer} an equal.]
The quality or condition of being equal or equivalent; A like
state or degree; equality; close correspondence; analogy; as
parity of reasoning. ``No parity of principle.'' --De
Quincey.
Equality of length and parity of numeration. --Sir T.
Browne.
From WordNet r 1.6 [wn]:
parity
n 1: (mathematics) a relation between a pair of integers: if both
integers are odd or both are even they have the same
parity; if one is odd and the other is even they have
different parity
2: (computer science) an error detection procedure in which a
bit (0 or 1) added to each group of bits so that it will
have either an odd number of 1's or an even number of 1's;
e.g., if the parity is odd then any group of bits that
arrives with an even number of 1's must contain an error
[syn: {parity bit}]
3: parity is conserved in a universe in which the laws of
physics are the same in a right-handed system of
coordinates as in a left-handed system [syn: {conservation
of parity}, {space-reflection symmetry}, {mirror symmetry}]
4: functional equality
From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]:
parity
An extra bit added to a {byte} or
{word} to reveal errors in storage (in {RAM} or {disk}) or
transmission. Even (odd) parity means that the parity bit is
set so that there are an even (odd) number of one bits in the
word including the parity bit. A single parity bit can only
reveal single bit errors since if an even number of bits are
wrong then the parity bit will not change. Moreover, it is
not possible to tell which bit is wrong as it is with more
sophisticated {error detection and correction} systems.
See also {longditudinal parity}, {checksum}, {cyclic
redundancy check}.

1. Pathol.

b. the cause or origin of a disease.

I COULD BE WRONG SO PLEASE CORRECT ME IF I AM.......
WHAT THIS SAYS TO ME IS THAT A MAJOR FACTOR IS THE SEX OF THE PERSON, AND THIS THUS PROVIDES DIFFERENCES MABYE RELATED TO EACH SEX. BOTH BEING SEX AND SYMPTOMS CAN BE IMPORTANT TO THE STUDY OF THIS DISEASE. I.E. HEART ATTACK RISK INCREASES WITH AGE. IRON USAGE IS AN ISSUE WITH THE ATTACKS. MEN AFTER A CERTAIN AGE, 40-45, STOP GETTING RID OF IRON AT A GOOD RATE, THUS STORING IN THEIR BODIES AND CAUSING PROBLEMS FOR THEM. WOMEN LOSE GREAT AMOUNTS OF IRON EACH MONTH BY DESIGN, BUT HAVE PROBLEMS LATER ON IN LIFE AND NEED SUPPLEMENT, BUT STILL HAVE SOME IRON RELATED HEART ISSUES. RLS SUFFERS HAVE A TOTAL IRON ISSUE. CAN'T USE IT PROPERLY, EVEN IF GIVEN ENOUGH OR HIGH DOSES.
THUS, IRON IS A FACTOR EFFECTING BOTH EQUALLY, BUT IS EQUALLY DIFFERENT FOR EACH SEX.
