In humans, normal females have XX chromosomes, and males have XY.
It is the presence of a Y chromosome that makes an individual a male, not the ratio of X to Y or the presence of only one X. Therefore someone with XXY would be male.

Sex determination in the unborn baby?

What is the female chromosome?
The X chromosome is one of the two sex-determiningchromosomes in many animal species, including mammals (the other is the Y chromosome). It is a part of the XY sex-determination system and X0 sex-determination system. The X chromosome was named for its unique properties by early researchers, and this resulted in its counterpart being named the Y chromosome for the next letter in the alphabet when it was discovered later.
What does an x and y chromosome identify?
In the cytological terminology x and y chromosomes are identified as sex chromosomes. In human being these chromosomes are responsible for determination of sex in the offspring.
What is a sex linked dominant inheritance pattern?
Only in life with the XX XY sex determination system.A change in the X chromosome of a cell. Females have two copies of the X chromosome, so they can replace it, however, the Y chromosome in males does not contain as much material, so it cannot be replaced.
How are autosomes similar to sex chromosomes?

What are the x and y chromazones?

X chromosome
In humans what are the chromosome pairs 1 through 22 called?
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
What determines the sex of an organism-?
The sex chromosomes determine the sex of an organism. In humans, it is the 23 pair. Females pass on either or their X chromosomes, while males pass on either their X or their Y. If the male passes on their X chromosome, the resulting offspring is female. If they pass on their Y chromosome, the resulting offspring is male.
How do you determine to give birth to a male?
You cannot control the sex of a fetus through determination alone. The mother donates an X chromosome via her egg. The sperm donated by the male partner, which can contain an X or Y chromosome, determines the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).http://www.science20.com/news_releases/chromosomes_are_so_20th_century_male_genes_really_determine_baby_gender_says_study#ixzz3eHLpJJRt
