There is a theory that human sex determination occurs because the X chromosome is inactivated. The article cited below hypothesizes that this theory is true and assumes that in order for males to receive "masculine" characteristics, their Y chromosomes would need to preferentially mediate structural genes that create those masculine characteristics. But they cannot mediate like that if X chromosomes also mediate those strutural genes. Hence, it is put forward that X chromosomes must be inactivated to in order to create masculine characteristics.



Since the two major theories regarding sex determination don't have much evidence to support them. This article states that the reason behind sex determination has to do with the dominant way in which the gonads develop. The argument isn't yet as clear to me as I'd like, but I feel that once I read this article a few more times, it'll yield promising results.
