Question

True hermaphroditism karyotype:

• A. 45 XO streaked gonads
• B. 46 XX Ovotestis
• C. 47 XY+9
• D. 47 XX

Answer 1

The Correct Option is B

True hermaphroditism, also known as ovotesticular disorder of sex development (DSD), is a condition where an individual possesses both ovarian and testicular tissue. The most common karyotype associated with true hermaphroditism is 46 XX, which means the person has two X chromosomes, typically associated with a female chromosomal pattern.

Explanation:

• A karyotype of 46 XX Ovotestis indicates that the individual has tissues that can develop into either ovarian or testicular structures, which is characteristic of true hermaphroditism. This karyotype has both structures within the same individual despite being genetically female.
• Option 45 XO streaked gonads refers to Turner syndrome, characterized by the presence of a single X chromosome and underdeveloped (streak) gonads.
• Option 47 XY+9 depicts a chromosomal abnormality with an extra chromosome, which does not typically relate to hermaphroditism.
• Option 47 XX is not valid as the presence of an additional chromosome (indicating 47 chromosomes) does not define true hermaphroditism.

Therefore, the correct answer is 46 XX Ovotestis.
