The sex chromosome that in female mammals is paired with another X-chromosome and in males is paired with a Y-chromosome. Very few genes on the X-chromosome have counterparts on the Y-chromosome, and since males have only one X-chromosome, any gene present on it (even if the gene is recessive in females) is expressed in males. In females, one of the two X-chromosomes in each cell is deactivated.

Origin of x-chromosome

  • Named by Hermann Henking in 1890 from x (signifying the unknown) due to some baffling properties he had observed. The brief resemblance in the appearance of the X chromosome to the letter "X" during cell division is entirely coincidental.
