There may not be enough factor made. The person will have a bleeding disorder. What type the person has depends on which gene has the defect. A sex-linked gene is any gene that is found on the sex chromosome labeled X. The instructions that these genes give are called sex-linked traits. If a defective gene is on the X chromosome, it is called a sex-linked disorder.
It will occur almost exclusively in men. Hemophilia and color blindness are both sex-linked disorders. The genes that cause them are on the X chromosome. The 22 pairs of chromosomes that are not the sex chromosomes are called autosomes. If a disorder is carried by a gene on one of these autosomes, it is called an autosomal disorder. Since it is on the autosome and not the sex chromosomes, it can occur in both males and females. When the 23 chromosomes from the father's sperm and the 23 from the mother's egg meet, they pair up.
The genes on the chromosomes pair up, too. The paired genes, one from each parent, carry the plans for the same part of the body.
For instance, the gene for hair color from the father pairs up with the gene for hair color from the mother. Sometimes one of the genes in the pair is stronger and blocks the instructions from the other gene. The stronger gene that takes control is said to be dominant. The gene whose instructions are blocked is called recessive. A recessive gene will have a chance to send its instructions to the cells only if it is paired with another recessive gene. Suppose a child receives a gene for brown eyes from one parent and a gene for blue eyes from the other parent.
Since the gene for brown eyes is the dominant gene, the child will have brown eyes. The child will still carry the recessive gene for blue eyes and may pass it on to his or her children.
For each gene pair, a child can inherit two dominant genes, two recessive genes, or one dominant and one recessive gene. How is vsepr used to classify molecules?
