Question

Find out the mismatched pair.

• A. Haemophilia - Sex linked recessive
• B. Cystic fibrosis - Autosomal recessive
• C. Downs syndrome - Trisomy 21
• D. Turners syndrome - Y-linked

Answer 1

The correct option is D Turners syndrome - Y-linked

• Turners syndrome is also known as 45, X or 45, X0, is a condition in which a female is partly or completely missing an X chromosome. It does not involve the Y chromosome as it is a condition arising in females. It affects development in females.
• The most common feature of Turner syndrome is short stature, which becomes evident by about age 5.
• An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common.
• So, the correct answer is 'Turners syndrome - Y-linked'.
