A very biased study was done in the 60's and 70's which incorrectly assumed certain behavior traits such as tallness and aggressive behaviour. The media exaggerated the traits in books and tv programs so that the general public was grossly misinformed. Today, we know that 47, XYY karyotypes are normal individuals with normal behavior and normal physical traits and is it a disservice to those who have the the extra y to be stigmatized in any other way but normal.

How many barr bodies are found in an extra y chromosome?
Barr bodies are inactivated X chromosomes found in females, and males typically do not have Barr bodies since they have one X and one Y chromosome. In the case of an individual with an extra Y chromosome (for example, XYY syndrome), there are no Barr bodies present, as Barr bodies are formed from X chromosomes only. Therefore, the presence of an extra Y chromosome does not contribute to Barr body formation.
What does it mean when someone has an extra chromosome?
If someone has an extra chromosome it means there was a genetic mutation that is abnormal in human development. It may result in problems with the person affecting them on a basic level, or may go fully unnoticed. A common disorder that can be caused by having an extra chromosome is Down's Syndrome.
How could a zygote be produced with an XYY karyotype?
An XYY zygote can be formed if a pair of sex chromosomes fails to separate during meiosis, so the gamete formed has both the X and Y chromosomes. This gamete would then meet the other gamete from the other cell that would contain a Y sex chromosome. The resulting zygote that is formed would have XYY sex chromosomes. This abnormalty where there is an extra chromosome or is missing a chromosome is called nondisjunction.
What chromosome is the sex determining chromosome?
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
What are examples of genetic disorders that is caused by insertion of extra codons in the x sex chromosome?
The phenomenon of having an extra chromsome is called anueploidy. Depending on the chromosome of which the extra copy exists, there are many disorders.Down Snydrome is the most common disorder associated with an extra autosomal chromosome, but it is not the only one. The other condintions that come from extra copies of an autosome (non-sex chromosome) that result in the most live births are:Edward's Syndrome from an extra copy of 18 andPatau syndrome which is caused by an extra 13.As for sex chromosomes,an extra X chromosome results in Klinefelter's syndrome (XXY) in males andmetafemale or XXX syndrome in women.Males with an extra Y are simply refered to as having XYY syndrome.

What is 48xxyy?
48,XXYY syndrome is a sex chromosome anomaly in which males have an extra X and Y chromosome. AKA Polyploidy

How is Jacobs syndrome inherited?
It's not. Jacob, XYY, syndrome is completely random disease; unlike most genetic diseases. It is caused by the accidental inheritance of an extra Y chromosome. Typically a father only gives one Y chromosome, but one mistake can cause a sperm to to carry that extra chromosome.
What does syndrome mean?
This is a birth defect. A person born with this has an extra chromosome 21.
What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
What is the term for an individual who has an extra copy of one chromosome or is missing a chromosome - Is it something-'ploid'?
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
Why is x chromosome called x?
An X chromosome is known as an X chromosome based on its shape, which resembles an X. The Y chromosome resembles a Y.
What are the x and y chromazones?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )

Why is the y chromosome useful for tracing ancestry?
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.
