- Hemophilia is a rare inherited disorder in which the blood does not clot normally.

- what is the definition of hemophilia?
- A: Above is not entirely correct, the bleeding will stop, it just varies on severity on how hard it is to stop.It is a genetic disorder which mainly affects males and is on the X chromosome (recessive), it is basically a genetic mutation which stops ‘clotting factor’ being produced (a normal person has say 100%, a person with severe/moderate haemophilia will have 1-5% of that, to put it into perspective)So yeah, they bleed more, but it is controllable and will eventually stop.
- If our genetics were formulated through natural selection, and natural selection only relays beneficial traits?
- Q: (continued) to the succeeding generations, the following traits must be beneficial.-various forms of cancer-M.S.-autism-diabetes-Angelman syndrome -Canavan disease -Celiac disease -Charcot-Marie-Tooth disease -Color blindness -Cri du chat -Cystic fibrosis -Down syndrome -Duchenne muscular dystrophy -Haemophilia -Klinefelter syndrome -Neurofibromatosis -Phenylketonuria -Prader-Willi syndrome -Sickle-cell disease-Tay-Sachs disease -Turner syndrome What’s up with that? These are beneficial? They must be, BY THE VERY DEFINITION THAT IS NATURAL SELECTION. What are your thoughts on that? Just curious. You don’t think that, I don’t know, the harmful things that we put into your bodies could be to blame for genetic mutations?Leave your dogma at the door…and petty insults.
- A: Well, several of the disorders you list aren’t inherited genetic diseases in the way you suggest.Down Syndrome is the result of an extra chromosome in the (normally) 21st pair, so it crops up at random. While there are some inheritable genetic defects that can predispose one to developing cancer, there are no cancers caused only by inherited genetic defects, just as there are no genetic defects that yield a 100% chance of developing cancer.Klinefelter and Turner syndrome are both the result of a malfunction in the gamete production process, so they cannot be weeded out. Autism has no definitive genetic cause, nor does diabetes.As others have pointed out, sickle-cell “disease” has a benefit which outweighs the possible drawbacks (it prevents malaria).Those syndromes on your list which are the result of an intergenerational inherited genetic defect are recessive. So long as one parent passes on a healthy copy of the gene, it does not matter if the other parent passes on a defective copy. The healthy copy overrides the defect and allows the organism (in most cases) to be perfectly viable.That has the happy effect of keeping the mortality rate to a minimum, but it also has the unfortunate effect of allowing these diseases to persist through the generations by allowing “carriers” to live and breed, potentially passing on the defective gene, until their offspring mates with another carrier, which allows the syndrome to manifest itself.By the way, that would also be why males are far more predisposed to a bevy of inheritable genetic diseases (such as color-blindness). Since they only have one X chromosome instead of two, any defect in the X chromosome they inherit will automatically express itself (whereas females have a second one that can override any defective genes).
