Human females have a homologous pair of X chromosomes (XX), but males have one X and one Y chromosome (XY).
X chromosome
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.
Valanga sp. sex is determined by using the XO system. This system use only one type of sex chromosome, the X. Females are XX while males have only one sex chromosome (XO). Sex of the offspring is determined by whether the sperm cell contain and X chromosome or no sex chromosome.
Although only males produce sperm, that does not mean that all sperm is male. There are two types of sperm: male and female. Male sperm carry the 'y' chromosome; female sperm carry the 'x' chromosome. If all sperm where male, then there would be no females born. Thus, the difference between male and female sperm is that male sperm carries the 'y' chromosome and produces male offspring and female sperm carries the 'x' chromosome and produces female offspring.
the autosome do not control the sex organs . but the sex chromosome control the sex organs
An autosome is any of the 23 chromosomes which is not an X or Y chromosome. A sex chromosome is effectively the same as an autosome, apart from depending upon whether you inherit a Y chromosome or not, a sex chromosome will determine your gender. Hence the name.

The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
The 23rd chromosome in human DNA is called the sex chromosome, and it determines the gender of the baby. A chromosome of XX is unique to girls, and XY is for boys. http://www.genome.gov/10001772 This link is to the National Human Genome Research Institute, for more in-depth information.
X chromosome
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 )
