People with Klinefert´s syndrome have one barr body.
Yes , the number of barr bodies in a cell is always equal to the number of X chromosomes minus one. For example in the XXY chromosome there is one Barr body

No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.
How does Klinefelter's syndrome affect the person?
The X chromosome is affected, because there are 2 of them (and a Y chromosome).
Is Angelman syndrome the same as Down syndrome?
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
Do all serial killers suffer from Klinefelters Syndrome?
The corralation of serial killers and Klinefelter's Syndrome is intriguing but unproven. Named for Harry F. Klinefelter in 1942, defined as the condition of an extra chromosome (female) in males. Most people know that an extra chromosome will result in Downs Syndrome, but few know about Klinefelters. The condition became better-known at the murder trial of New York serial killer Arthur Shawcross. It was used by his defense attorney as an explaination of his client's violence against prostitutes. Other killers that have this condition are:Carl Panzram, Francis Heaulme, Bobby Joe Long, and Richard Speck.* Further scientific study will be needed before this theory is indeed a fact. *This is not a complete list.
Turner's syndrome always results in female offsprings why?
Because people who have Turner syndrome have one X chromosome instead of the two other females have. As they do not have a Y chromosome, they are female.
How do the cells of people with down syndrom differ from those of others?
People with down syndrome have cells with an extra chromosome 21.
Is down syndrome a mutation?
Down Syndrome is caused by extra genetic material on Chromosome 21. About half of the children of people who have Down Syndrome are born with Down Syndrome themselves. See the Related Linksbelow to view an article about the genetics of Down Syndrome.
Who are the people who have turner's syndrome?
It is a type of genetic disorder in which females are affected. This happens when they dont have an X chromosome as in the sex chromosome so the resultant will be XO.
People with down syndrome have how many chromosomes?
47There are 47 chromosomes in someone with Down syndrome; the 21st pair has an extra chromosome. Most people have 46 chromosomes. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes on their 21st pair.
Does klinefelter syndrome skip a generation?
No, as people with Klinefelter's syndrome cannot have children and so there would not be another generation. (That is not entirely true, while it is true Klinefelters causes an extra chromosome sperm maybe be found via a testicular extraction in minute amounts. If this is the case you can father a biological child though the chances are small it is not impossible and more and more Klinefelter men are becoming dads. We can also adopt, and while I understand the authors point - the child would be ours and therefore carry our name and continue the generation. Klinefelters IS NOT hereditary. Hope this helped.
How many copies of Chromosome 21 are there in someone who has Down syndrome?
3 Pairs of Chromosome 21There are 47 chromosomes in someone with Down syndrome (most people have 46); the 21st pair has an extra chromosome. Down syndrome is also known as "Trisomy 21" - a reference to the fact that someone with Down syndrome has 3 pairs of chromosomes 21.
How do cells of people with Down syndrome differ from those of others?
