The X chromosome is about three times larger than the Y chromosome containing about 900 genes while the Y chromosome has about 55 genes. Female mammals have two X chromosomes in every cell. However one of the X chromosomes is inactivated .
The X chromosome is one of the two sex-determining chromosomes in many organisms including mammals (the other is the Y chromosome) and is found in both males and females. 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 which resulted in the naming of its counterpart Y chromosome for the next letter in the alphabet following its subsequent discovery.
The X chromosome is one of two sex chromosomes. Humans and most mammals have two sex chromosomes the X and Y. Females have two X chromosomes in their cells while males have X and Y chromosomes in their cells. Egg cells all contain an X chromosome while sperm cells contain an X or a Y chromosome.
The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome ). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells.
