PROOF NO GENDER IDENTITY There are many kinds of sexual birth defects but in the end everyone is either male or female. If they can have children, they are male or female. There has never been anyone who functioned REPRODUCTIVELY as both male and female. If they cannot have children, they are still either male or female. ¶ Gender may need to be determined by DNA testing. (Now, the rest of this article may confuse some of our readers. If so, they can jump to the conclusion at the end of the article.) In some cases a person may have an extra chromosome but they are still male or female. XXX is female. XXY is male. XYY is male. Any chromosomal combination of XX with one or more extra X chromosomes is female. Any chromosomal combination of XY with one or more extra Y chomosomes is male. There are no human beings with all Y chromosomes. (As a footnote, we add that we have read about XXXX, XXXXX, XYYY and XYYYY chromosomal combinations. Also, a person can have a “zY chromosome,” which is part weak X and part strong Y. In this case, the Y part determines function and the person is male. [The chromosome pair is XX where one of the Xs is actually a zY chromosome.] There is also a “zX chromosome” which is part strong X and part weak Y. In this case, the X part determines function and the person is female. [The chromosome pair is XY where the Y is actually a zX chromosome.] Also, a person can have both XX and XY chromosomes in different parts of their body. In this case, nerve DNA is used since a nerve is effectively a part of the brain and the brain controls how the rest of the body functions including sexually. Also, one must be sure the DNA test is a Sigma DNA test, which tests for chromosome part strength, not a Delta DNA test, which does not test for chromosome part strength.) ¶ CONCLUSION: In simple terms, if there is no Y chromosome or strong Y chromosome part the person is female and if there is a Y chromosome or strong Y chromosome part the person is male.
