Why aren't somatic mutations passed on to the next generation?
most genes mutations are recessive, and since most organisms have two of every genes, the normal genes will dominate the recessive genes.
How are mutations returned to normal in an organism?
Mutations on recessive genes return to normal in an organism
Is hemophilia a mutation?
Mutations in the F8 and F9 genes cause hemophilia. Changes in the F8 gene are responsible for hemophilia A, while mutations in the F9 gene cause hemophilia B. The F8 gene provides instructions for making a protein called coagulation factor VIII. A related protein, coagulation factor IX, is produced from the F9 gene. Coagulation factors are proteins that work together in the clotting process. After an injury, blood clots protect the body by sealing off damaged blood vessels and preventing further blood loss. Mutations in the F8 or F9 gene lead to the production of an abnormal version of coagulation factor VIII or coagulation factor IX. The altered protein cannot participate effectively in the blood clotting process and, in some cases, the protein does not work at all. A shortage of either protein prevents clots from forming properly in response to injury. These problems with blood clotting lead to excessive bleeding that can be difficult to control. Some mutations almost completely eliminate the activity of coagulation factor VIII or coagulation factor IX, resulting in severe hemophilia. Other mutations reduce but do not eliminate the activity of one of these proteins, which usually causes mild or moderate hemophilia. The other, rare form of this condition, acquired hemophilia, results when the body makes specialized proteins called autoantibodies that attack and disable coagulation factor VIII. The production of autoantibodies is sometimes associated with pregnancy, immune system disorders, cancer, or allergic reactions to certain drugs. In about half of cases, the cause of acquired hemophilia is unknown. Read more about the F8 and F9 genes. Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation must be present in both copies of the gene to cause the disorder. Males are affected by X-linked recessive disorders much more frequently than females. A striking characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. In X-linked recessive inheritance, a female with one altered copy of the gene in each cell is called a carrier. She can pass on the altered gene to her children, but usually does not experience signs and symptoms of the disorder. In about 10 percent of cases, however, females who carry one altered copy of the F8 or F9 gene will experience mild problems with bleeding. From: http://ghr.nlm.nih.gov/condition=hemophilia
What do Multifactoral Disorders usually result from?
mutations in multiple genes
Do autosomes have lethal recessive genes?
Yes. Autosomes CAN have lethal recessive genes, but that does not mean they always contain recessive mutations.
Does F7 F8 F9 or F10 forces a NOW function in Excel?
No, none of them do that. F7 starts a spell check. F8 starts a selection. F9 recalculates the spreadsheet. F10 starts the menu system.
