This modification of gene expression is called dosage compensation. If diagnosed in early childhood, regular injections of human growth hormones can increase their stature by a few inches. Males with Down syndrome sometimes also have Klinefelter syndrome. The most usual cause is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve. They generally lack prominent female secondary sexual characteristics. The two copies may be the same, or they may be different. A functional second copy can often work well enough on its own, acting as a sort of back-up to prevent problems. In such systems, it is believed that a male or female develops based on the ratio between X chromosomes and the number of sets of autosomes. The extra genetic material in these cases can lead to skeletal abnormalities, decreased IQ, and delayed development, but the features of these conditions are variable. Women, with the gene expressed by both the active and inactive X chromosomes, would still have a functioning copy. Though these two chromosomes pair with each other during meiosis, there is usually very minimal homology or recombination between them, primarily because of a large difference in their genetic content and size. Most fragile-X males have large testes, big ears, narrow faces, and sensory processing disorders that result in learning disabilities. A mother who carries an X-linked dominant disorder can pass on her illness to fifty percent of her daughters and fifty percent of her sons. He was sentenced to life in prison where he eventually died. Male birds make sperm, which always have a Z chromosome.
