Just to be clear:

"....AND THE GENE IS..............??????"

Goofup, it is no specific single gene, but a combination of genes—like many inheritable traits. It appears to be a recessive gene, and it also appears to be carried by some females of a particular line, and it is not believed to affect them as far as sexual orientation is concerned. It operates sporadically and has to do with the timing of hormones released to the fetus in utero. The actually physical organs of sex are established by the Y chromosome, which is carried by the father.

Here is yet another example of your abysmal ignorance:

"….and it falls under what race, creed or color?"

The gene in question is independent of genes that determine race.

Race is considered to be an anthropological category and often determines skin color and certain other physical characteristics. So "race" and "color" are actually redundant. Creed, on the other hand, is NOT genetic. That IS, indeed, a matter of choice.

Are you really that ignorant?
