X Chromosome May Leave a Mark On Male Fertility

sciencehabit writes "Behind every great man, the saying goes, there's a great woman. And behind every sperm, there may be an X chromosome gene. In humans, the Y chromosome makes men, men, or so researchers have thought: It contains genes that are responsible for sex determination, male development, and male fertility. But now a team has discovered that X—'the female chromosome'—could also play a significant role in maleness. It contains scores of genes that are active only in tissue destined to become sperm. The finding shakes up our ideas about how sex chromosomes influence gender and also suggests that at least some parts of the X chromosome are playing an unexpectedly dynamic role in evolution."

The X chromosome is, for the most part, just another part of the genome; it contains all sorts of random junk, like blood clotting factors and parts of the receptors in our eyes that let us see colour. Any disease you've ever heard of that's "X-linked" or more common in men than women is either affected or effected, directly or indirectly, by the X chromosome. It is of no significance or note whatsoever that it contains stuff that's only activated in the male body.

      If you want something weird and sex-linked to rant insanely about, however, there's always the mystery of digit ratio.

In the stereotypical portrayal of hunter-gather societies, certainly it is desirable to have slightly more women than men; the traditional division of responsibilities leaves the women with more consistent work. Contrariwise it would seem that an agrarian society would benefit more from a surplus of men to work fields, but there are relatively few adaptations in our genomes that are agriculture-oriented.

      There's nothing wrong here; it's just a simple misunderstanding by the journalist. We've known about X-linked for as long we've known about sex chromosomes, which inherently implies that the X chromosome has responsibilities beyond determining sex.

      Believe it or not, however, there are actually advantages to the Y chromosome being so minimal. Men are nature's beta testers: sometimes mutations in the X chromosome have significant benefits, and as these traits aren't balanced out by a second allele, they become more pronounced and hence are easier to detect during sexual and natural selection. This is (probably) why men display a greater variance in height, strength, and analytical skill. Similarly, by always suffering from a disease, and hence by not getting laid, men protect the rest of the tribe from the disorders they end up with.

    The Y chromosome is a li'l runt and they think it won't even be there anymore in a hunnert thousand years or so.

    I don't think there's anyone who takes this seriously any more. There were some people suggesting that if genes are lost at a linear rate off the Y chromosome, it should disappear in another 10 million years. However, chimpanzees and humans show no difference in the number of genes on the Y chromosome since we diverged 6-7 million years ago, and we've both only lost one gene since we diverged from the rhesus macaque 25 mya. Given that sequencing of the platypus genome puts the common mammalian Y chromosome at a max of age of 166 mya, this suggests the linear model is just wrong.

    The Wikipedia has good article on this from which I drew my numbers, if you're interested in more.

      Some species use the number of X chromosomes. Reptiles and avians use ZW chromosomes, where the "female chromosome" is the shorter, degenerate one. Ants and bees are just kind of weird. The platypus has something like 10 sex chromosomes and lacks the SRY gene, so we have no idea how it really works AFAIK, and platyfish (unrelated) have some sort of weird W/X/Y system.

If a man and a feminist need to pass through that door, if the man opens and holds the door for the feminist, he is sexist. We have basically the same solution to the same problem, but the sexist feminist refuses to acknowledge that the solution is the CORRECT solution.

    MOST WOMEN will just accept this trivial act of consideration with a nod of gratitude, or a word of thanks, and go on about their business. SOME FEMINISTS will want to kick the man in the balls for being sexist.

    Sadly, I've personally heard actual feminists make equally-stupid arguments. One particular instance I recall was discrediting a physical-fitness study because it separated male and female participants. The study's conclusion had nothing to do with gender differences, but segregating the samples eliminated a variable. That didn't matter to the opposing extremist, though. She argued that since the male and female results were separated, each group was therefore subject to different biases, and the whole study should be rejected because it was "clearly" just a piece of propaganda to further the myth that men are physically superior to women.

    Of course, in the actual study, there were a good many outliers that overlapped. Speaking of outliers, there are also extremists on all sides of an argument, even the ones with supposed moral high ground. Such extremists should be ignored as an anomaly, and the real science can go on uninterrupted.
