Question
Short note : Turner syndrome.
✓
Answer
Turner syndrome is a disorder arising in women due to abnormality in sex chromosomes.
Turner syndrome arises due to either inheritance of only one X chromosome from parents or due to inactivation of the gender- related part of X-chromosomes.
Instead of the normal 44 + XX condition, women suffering from Turner syndrome show a 44 + X condition.
Such women are sterile i.e. unable to have children due to improper growth of the reproductive organ.
