As this paper will discuss later, this assumption that male and female homosexuality can easily be compared may be entirely inaccurate.) it seemed that the majority of homosexual occurrences were on the maternal side of the tree. From this information, researchers concluded that if in fact there was a "homosexual gene", it appeared to be passed down from mother to son. This means that heterosexual females are carriers of this gene, and when it is passed down to a male child, there is a chance that the child will be a homosexual. While this study did not come up with any hard core facts about the genetics of homosexuality, it showed that a connection very well could exist. Since this study did determine that the gene influencing homosexuality was carried by the mother, researchers participating in further studies knew that they could limit their search to the X chromosome, and that is exactly what they did
