Document Summary

So the sperm carrying either x or y chromosomes is what determines the sex: genes: they for example regulate the production of melanin in the iries of the eye. Also determine the functions of each cell group. Genes are influenced by the biochemical environment surrounding them during development. Consider, for example that a child who inherits genes for tall stature may or may not be tall as an adult. Should he experience very poor nutrions for prolonged period early in life. It is usually colour blindness and it is because of a recessive gene that appears on the x chromosome. Recall that a normal (xy) male has only one x chromosome the one he inherited from his mother. If this x chromosome carries a recessive gene for colour blindness, the male will be colour-blind. Because there is no corresponding gene on his y chromo- some that might (cid:272)ou(cid:374)te(cid:396)a(cid:272)t the effe(cid:272)t of this (cid:862)(cid:272)olou(cid:396) (cid:271)li(cid:374)d(cid:863) allele.
