Which of the following character is wrong about Turner’s syndrome : A. Highly fertile female B. Presence of rudimentary ovaries C. Absence of one of the X chromosomes D. Lack of secondary sexual characters
Option A Turners syndrome occurs due absence of X chromosome. Individuals having a single X chromosome 2A+XO (45) have female sexual differentiation but ovaries are rudimentary. Other associated phenotypes of this condition are short stature, webbed-neck, broad chest, lack of secondary sexual characteristics and sterility. Thus, any imbalance in the copies of the sex chromosomes may disrupt the genetic information necessary for normal sexual development.
