Question

Females with Turner's syndrome have

• A. Small uterus
• B. Rudimentary ovaries
• C. Underdeveloped breasts
• D. All of the above
  

Answer 1

The correct option is D All of the above

Turners syndrome is due to monosomy (2n 1). It occurs by the union of an allosome free egg (22 + 0) and a normal X sperm or a normal egg and an allosperm free sperm (22 + 0).

Turners syndrome (most common type of female genetic disease) having XO genotype is caused by the absence of X chromosomes in female. These are sterile females with poorly developed ovaries, small uterus and underdeveloped breasts. They have webbed neck and broad chest. The individual has 2n = 45 chromosomes (44 + XO) instead of 46.

So, the correct answer is 'All of the above'.
