What kind of syndrome... I found this Velocardiofacial (Spritzen) syndrome, but I don't know if that's right.\n\nI know I am not helping much but all I can find is "SPRITZEN syndrome" but I haven't found an answer to your question

Ellis-van Creveld syndrome: A type of short stature with striking shortening of the ends of the extremities (arms and legs), polydactyly (extra digits), fusion of bones in the wrist, dystrophy (abnormal growth) of the fingernails, change in the upper lip variously called 'partial hare-lip,' 'lip-tie,' etc., and cardiac (heart) malformations. The teeth may already be erupted at birth (natal teeth) and fall out prematurely. \n\nThe Ellis-van Creveld (EvC) syndrome was first described by Drs. Richard W. B. Ellis of Edinburgh and Simon van Creveld of Amsterdam. Each had a patient with this syndrome, as they had discovered when they met in the same train compartment on the way to a pediatrics conference in England in the late 1930s.

That's not normal.  He needs to go see his doctor that ordered the test.  It could be infection, or even a blood clot.

The mechanism for an abnormal amount of X or Y is called nondisjunction in meiosis of cellular division. However there is no possible way for a man to father only one gender.\n\nHaving only a Y is not enough DNA for viable offspring, so the gamete automatically aborts.\n\nHaving only an X results in a female with a condition called Turner's Syndrome. This will not cause a phenomenon of having only boys or only girls because the female does not choose the gender anyway.\n\nThe only possible way for a man to have a higher possibility of having boys is if he has an extra Y chromosome (XYY) caused by nondisjunction. Then the chances that the offspring is a girl is 33% and the chances of having a boy is 67%.\n\nAnd in case you were wondering, a male with XYY has Kleinfelter's syndrome and is infertile.\n\nAlso, you're saying that you have examples from literature, which may not be reality. It's highly unlikely that a father has 15 children of the same gender. I'd say literature tends to exagerate :)

Probably has to do with x & Y chromosomes has to do with genetics to make baby a boy or girl

The red blood cells contain SS hemoglobin, an abnormal form, and will go into crisis with sludging of blood in small arteries and arterioles throught the body causing severe pain and often death if not treated properly.

go to google and type in genetic disorders and then take your pick. I thought young kids were supposed to be so computer savy!

Sirenomelia is a rare congenital disorder can result in a child with legs fused together and the genitalia reduced. Because of the similarity to the legendary mermaids, it is called "mermaid syndrome" or "sirenomelia". This condition is about as rare as conjoined twins and is usually fatal within a day or two of birth because of kidney and bladder complications. There are two known survivors of this disorder alive today.

Scientists have reported that they've found an "extremely unusual" trait in the cells of some mothers with two or more gay sons, providing more evidence to suggest that homosexuality might be inherited.\n\n\nMothers of multiple gay sons were about six times more likely than other women to process their X chromosomes in a certain way, researchers discovered.\n\n\nResearchers aren't entirely sure what the findings mean, said study co-author Sven Bocklandt, a postdoctoral researcher at UCLA. Making things more complicated, about 75 percent of mothers of multiple gay sons don't have the trait.\n\n\nStill, the study, released Tuesday in the journal Human Genetics, raises plenty of questions, Bocklandt said, especially as researchers try to figure out whether homosexuality has genetic roots and if there truly is a "gay gene" -- or genes.\n\n\n"What everybody wants is the gene, and we don’t have it yet," Bocklandt said. "But this is an independent confirmation that the X chromosome is involved."\n\n\nBocklandt and colleagues looked at a phenomenon known as X-chromosome inactivation, in which cells inside the bodies of females automatically turn off -- or inactivate -- one of their two X chromosomes. That leaves them with one working X chromosome -- just like males, who have a single X and a single Y chromosome.\n\n\nNormally, each cell in a female's body randomly turns off one or the other X chromosome. In some cases, such as when families share a genetic disease, there is "extreme skewing" -- one X chromosome is more likely to be turned off than the other, Bocklandt said.\n\n\nIn the new study, the researchers looked at 97 mothers of one or more gay sons and 103 women with no gay sons to see what their blood cells did with their X chromosomes. The researchers recruited many of the women with the help of PFLAG.\n\n\nThey found that nearly a quarter of the mothers of multiple gay sons inactivated the same X chromosome -- in other words, nonrandomly -- compared to just 4 percent of the women without gay sons. Of those with one gay son, 13 percent inactivated the same X chromosome.\n\n\nDr. Ionel Sandovici, a genetics researcher at the Babraham Institute in Cambridge, England, who is familiar with the research findings, cautioned that the study is small, with just 44 mothers of multiple gay sons being examined. More research in larger groups must be done to confirm the results, Sandovici said.\n\n\nThe research does provide "circumstantial evidence" that the X chromosome contributes to the development of male sexuality, Sandovici said. But "we still understand very little about molecular mechanisms of sexual orientation, and this seems to be rather a complicated biological puzzle."\n\nBut of course its Nature vs. Nurture and its possible that the person could just become gay because of his environment/experiences or just be born that way.

creutzfelt-jacob disease its a nuerological diseas caused by an infectios protien, its no the opposite, its very similar, it make you crazy and convulsive.

I am not for sure.  I know a person with M.S. can't....tell him to call a blood bank and ask them; they'd know.

Its called Androgen Insensitivity Syndrome.

C. The male will only have one X chromosome so there is no way it can be expressed over a homozygous normal XX of a female
