What happens if a baby has 2 x chromosomes and a y chromosome?
In humans, it is the presence of the Y chromosome that makes an individual a male (not the ratio of X to Y). A normal male will have the sex chromosomes XY. It is possible for males to have either an extra X chromosome, XXY, or an extra Y chromosome, XYY. These are both a type of aneuploidy - an unusual number of chromosomes. XYY males are not very different from XY ("normal") males. They have normal testosterone levels, normal intelligence and normal fertility. They are on average taller than XY males. XYY usually results from an error when sperm cells are formed, which results in a sperm cell that contains 2 Y chromosomes. This combines with the female gamete, which carries an X chromosome - resulting in an XYY individual.
Why did the XYY chromosome theory fall out of favor as an explanation for criminal behavior?
The XYY chromosome theory fell out of favor as an explanation for criminal behavior because subsequent research did not support a direct link between XYY genotype and criminal behavior. It was found that the association was weak and other factors such as social environment and upbringing play a more significant role in shaping criminal behavior.
What is the cause of xyy syndrome and genetics?
XYY syndrome is caused by an extra Y chromosome in males. This condition typically occurs due to a random error in cell division during either the formation of the sperm or the egg. It is not inherited and does not have a clear genetic cause.
What does is mean to have a extra y chromosome?
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.
Is xeroderma pigmentosum dominant or recessive?
XYY syndrome can be said to be "dominant" because if a person has it, they have it. there is no having a recessive gene for this. However, technically, it is neither. XYY syndrome is not inherited, and usually occurs at random during formation of sperm cells. This happens as an error in Chromosome separation during Metaphase II. Sometimes it happens as a result of nondisjunction during cell division during a post-zygotic mitosis in embryonic development. This produces 46,XY/47,XYY.
Who discovered xyy syndrome?

How many chromosomes are there in a xyy male body cell?
You would have 47 chromosomes because you would have the normal 46 but one extra y with the sex determing pair of chromosomes which would make you have super male syndrome.
How many sexes are possible in chromosomes?
There are seven possible genetic sexes: XX = female XY = male X = female with Turner syndrome XXX = female with X-trisomy XXY = intersex with Klinefelter syndrome XYY = male with 47,XYY syndrome XXYY = male with 48,XXYY syndrome
What is the current research on XYY syndrome?
Current research on XYY syndrome is focused on understanding the link between the extra Y chromosome and the associated physical and behavioral characteristics of individuals with the condition. Studies are also exploring potential treatments and interventions to address the challenges that individuals with XYY syndrome may face, such as learning difficulties and behavioral issues. Additionally, research is investigating the genetic mechanisms underlying XYY syndrome to improve diagnosis and management of the condition.

How old was Alexander Fleming when he made pencillin?
Alexander Fleming was 47 years old when he discovered penicillin in 1928.
How do you solve for a variable if there are more than one of that same variable in the equation For example how would I solve xyy 4 for the variable y?
Assuming you meant to insert an = between xyy and 4, then xyy=4. Divide by x to get yy=4/x. yy is y^2, so y^2=4/x. Take the square root of both sides to get y=±√(4/x)
