Blood type and sexual orientation
Researchers in North Dakota studied eye color, hair color, blood type and Rhesus factor in a population of 7,000 students, gay and straight. While they found no correlation between sexual orientation and eye color or hair color, they did find a correlation for blood types.
An unusually high proportion of gays and lesbians were Rh- when compared to heterosexuals.
In addition, heterosexuals men and women had the same rate of Type A blood while gay men had lower incidence of the A blood type and lesbians had a higher incidence of the A blood type.

Eye color, hair color, blood type, and the rhesus factor: exploring possible genetic links to sexual orientation.

The present study sought to expand the limited evidence that sexual orientation is influenced by genetic factors. This was accomplished by seeking statistical differences between heterosexuals and homosexuals for four traits that are known to be genetically determined: eye color, natural hair color, blood type, and the Rhesus factor.

Using a sample of over 7,000 U.S. and Canadian college students supplemented with additional homosexual subjects obtained through internet contacts, we found no significant differences between heterosexuals and homosexuals regarding eye color or hair color.

In the case of blood type and the Rh factor, however, interesting patterns emerged. Heterosexual males and females exhibited statistically identical frequencies of the A blood type, while gay men exhibited a relatively low incidence and lesbians had a relatively high incidence (p < .05).

In the case of the Rh factor, unusually high proportions of homosexuals of both sexes were Rh- when compared to heterosexuals (p < .06).

The findings suggest that a connection may exist between sexual orientation and genes both on chromosome 9 (where blood type is determined) and on chromosome 1 (where the Rh factor is regulated).

I don’t believe that – I’m as gay as can be and I’m AB+

Hi Ron
Perhaps a little explanation is in order. This article is not saying that every gay person is Rh-. It only says that there is a higher rate of being Rh- among gay people and that the difference in that rate compared to heterosexuals is statistically different.

I will see if I can get the entire article and see if it gives the actual numbers.
Thanks for stopping by. 🙂

Hello, I am gay with pride. It is just a blood type like any. There can be a guy with blood type O who are gays, also A, B, AB, are other types of guys can be gays, bisexuals, transsexuals, transgenders, homosexuals, or heterosexuals. Blood do not consist of being gay. Blood is just blood. I have had many types of gays friends with different varieties of races. Blood does not mean anything. It is just simple.

I am not gay, neither straight nor I am a woman. I am A positive. I used to be golden curly hair as far as the time changed became brown hair but I have some blond highlights even in my eyebrows and some hidden golden hair under my hair, but mostly is brown hair and I have crystal brown eyes, and curly eyelashes, and pale, 5’10, with a small penis as 8 inches and a half size, and average body, and intelligent and mostly I am individual and alone who has not met already a friend like me, which is the most hardly part to find a friend like me. I believe it has to be part of blood to attract people to find friends or a boyfriend.
