What happens if a baby has 2 x chromosomes and a y chromosome?
This condition is known as Klinefelter syndrome, where a male is born with an extra X chromosome (XXY). Individuals with Klinefelter syndrome may have physical characteristics such as taller stature and reduced fertility. They may also experience hormonal and developmental differences compared to typically developing males.
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?
Having an extra Y chromosome, known as XYY syndrome, occurs in males and can be associated with increased height, delayed development, and learning difficulties. This genetic condition is typically not diagnosed until adulthood and most individuals with XYY syndrome lead healthy lives with no major medical concerns.
Is xeroderma pigmentosum dominant or recessive?
Xeroderma pigmentosum is a rare genetic disorder that is typically inherited in an autosomal recessive pattern, meaning that an affected individual must inherit a copy of the mutated gene from both parents. This disorder results in a deficiency in repairing DNA damage caused by ultraviolet (UV) light, leading to an increased risk of skin cancer and other skin abnormalities.
Who discovered xyy syndrome?
XYY syndrome was first discovered by Dr. Avery Sandberg and co-workers in 1961. They identified the presence of an extra Y chromosome in males.
How many chromosomes are there in a xyy male body cell?
A male with XYY syndrome has 47 chromosomes in their body cells, instead of the usual 46 chromosomes found in most human cells. This extra Y chromosome results in the condition known as XYY 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.
Who discovered Jacobsen Syndrome?
Jacobsen Syndrome was first described by Danish physician Petra Jacobsen in 1973. She noticed a distinctive set of symptoms in several patients and identified it as a distinct syndrome.

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)

What inherited syndrome is believed to be part of the make up of many serial killers?
