The Search For Human Chromosomes

Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age.

One of the greatest scientific feats of our era is the astonishing progress made in understanding the intricate machinery of life. We are living in the most productive phase so far in this quest, as researchers delve ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative new products.
