Chromosomes and Femininity?

Part of this week's reading uses biology to go against the normative ideas of what femininity is.  Angiers chapter 2 focused on chromosomes and began to explain the difference between the X and Y chromosome. There are two characters Keith and Adele, and Keith is read somewhere that the X chromosome is fat and floppy, while the Y chromosome is diverse.  He believed that this is reason for differences between men and women.  This is ridiculous in my opinion; one cannot base a sex of a human being on the bases of what the chromosomes look like!  He went on to say that men demonstrate at a microscopic level their edge over women because their chromosome is "diverse".  He also states that the Y is a "genetic innovation" that escaped the normative of the X chromosome.  In general what he was saying that X chromosome is dull and Y chromosomes are interesting.  Clearly he does not know much about biology because the X chromosome is more dominant and the largest of the 23 chromosomes (about 5-6 times larger).  Yes males add a change when their sperm bring to the egg the Y chromosome, but they can easily add an X chromosome as well. If the chromosome debate is to come into play as a determinate of masculinity and femininity, I say it’s a little ridiculous.  To look at it from that level is small but it does play a large part in development.  In my opinion many of our ideals of femininity and masculinity stem from society, and the way it is portrayed.  So for all the women out there, the X chromosome is larger and more dominant than Y, so we have nothing to be ashamed of!
