Two articles explore whether or not intelligence is linked to the X chromosome in a persons genetic makeup.

X Rated summary
Recent research regarding the X chromosome rank may help to define the biological differences between men and women. Sexual differences in intelligence were once thought to find primarily from hormones and the environment. Studies abide not found intelligence to be attributed to a single gene, but new discoveries may display that genes on the X chromosome may play a send out role. David Page, interim director of the Whitehead Institute for Biomedical inquiry in Cambridge, Massachusetts, admits that attempts to link enrichment of cognitive genes on the X chromosome to IQ differences are reasonable speculation.
Women receive two X chromosomes: one from each parent. However, men obtain a Y chromosome from the father and only one X chromosome from the mother. The Y chromosome bares genes that deal to invoke sperm production and other factors regarding male knowledgeable reproduction.
The X chromosome sports one thousand ninety-eight protein-carrying genes. Only 54 of the genes have functional counterparts found on the Y chromosome. When a gene on the X chromosome mutates in a adult female, the woman has another x chromosome to balance out the irregularity. Unfortunately, men do not possess an extra X chromosome to fix every errors that may arise from X chromosome mutations. The fact that males only have one X chromosome and few Y counterparts to match the X genes...
