There are only two genders! Comment?

According to Dr. Anne Fausto-Sterling, a recognized expert in this field of study, 1-1/2 to 2% of all births do not fall strictly within the tight definition of all-male or all-female, even if the child looks "normal." In reaching her numbers, Dr. Fausto-Sterling counted all incidents of intersexuality, from mild to extreme. The incidence of children with mixed genitalia is pegged at 1 in 2,000 to 1 in 3,000, or 0.033 to 0.05 percent of all births.

As far as chromosomes are concerned, we have observed genotypes involving XXX, XXY, XYY and X0 (Turner syndrome) sex chromosomes. And we've observed human phenotypes with a range from no functioning sex organs to varying amounts of male & female sex organs on the same individual (these are often called intersex). Genetic mosaicism is where the X and Y chromosomes are expressed differently (from the most common expression) on different partfs of the body (these phenotypes are also often described as intersex and sometimes hermaphrodite). Then there's androgen insensitivity syndrome. These are all observable biological phenomena that either God or Nature brings into the human family.
