The person would normally be female; however, males with Klinefelter's syndrome have at least two X chromosomes and at least one Y chromosome.
An organism with 2 X sex chromosomes is female.
The person would normally be female; however, males with Klinefelter's syndrome have at least two X chromosomes and at least one Y chromosome.
The X and Y chromosomes are called the "Sex Chromosomes". Both the X and Y chromosome are part of the "sex-determining system" that helps determine the sex characteristics in humans. In the system, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).
The person would normally be female; however, males with Klinefelter's syndrome have at least two X chromosomes and at least one Y chromosome.
A person's genetic sex is determined by the combination of sex chromosomes they inherit from their biological parents. Typically, individuals with two X chromosomes are female, while those with one X and one Y chromosome are male.
In Human Beings two chromosomes normally determine a persons sex. If a person has two X chromosomes, (XX), that person will be a female. If a person has an X and a Y chromosome, that person will be a male. Most people get 23 chromosomes from their mother and 23 from their father. Thus, most people have 46 chromosomes. They get either an X or a Y chromosome from their father. Sometimes things get complicated. That is for another answer.
If someone ends up with two x chromosomes (XX) Then they are a girl. If a person has one X chromosome and one Y chromosome(XY) then they are a boy. the men decide what sex the baby is since they have both an x and y. the women gives an x all the time.
Xy chromosomes= boy xx chromosomes= female
X and Y are the human sex chromosomes. Normal females have XX, normal males have XY. In humans, it is the presence of a Y chromosome that makes a person male, not the ratio to or number of X chromosomes. (Therefore a person with XXY would be male).
Females inherit two X chromosomes.
Humans have one pair of sex chromosomes. They are called X and Y. The two determine what sex a person will be. Males have X + Y and females have X + X. There are some genes that are called sex linked genes found on these. The Y chromosome is very small and contains mainly the genes that make a person a male. There are few other genes on the Y.
The two human sex chromosomes are called X and Y. Females carry two X chromosomes, and males carry one X and one Y.
