The author referred to the X and Y chromosomes as the misfit in the genome because they are not identical in size, comparable whatever other pairs. The X chromosome is the next largest after chromosome seven, the Y, merely is all a tiny piece of genetic material. eve in females, the two X chromosomes are not expressed in equal volume. At random, one of the X chromosomes clay inactivated and packs itself up in a tight bundle called the Barr body. oer the years, stud ies on the X and Y chromosomes revealed some strange and affect facts of genetics. We oftentimes think of genes as servants of the body, working together to arrive at the sinless organism. But the reality is a different story. The body is depict as the victim, plaything, involutionground and vehicle for the ambitions of genes.

(107) (slide 3) Here is a passage from a paper in the Science publication philosophic Transactions of the Royal Society: The mammalian Y chromosome is thereof likely to be engaged in a b come on in which it is appeargunned by its opponent. A logical consequence is that the Y sh ould run away and hide, shedding any transcr! ibed sequences that are not essential to its function. Even though it might not make sense right now, you could still pick out some unusual words such as contend opponent run away What could this possibly mean? This contrast between the X and Y first arrived when our ancestors switched from determining sex by the temperature of the egg, to determining it genetically.
