Women with Turner Syndrome (XO)and Normal Women (XX)are Clearly Different

Women with Turner syndrome (XO) and normal women (XX) are clearly different phenotypically.In addition, the vast majority of XO conceptions abort before birth.However, both XO and XX women have one active X chromosome since the X in XO women remains active and one might expect that they would therefore have similar phenotypes.What is the MOST reasonable explanation for their different phenotypes?

A) XO women do not have a copy of the SRY gene.
B) Some genes remain active on the inactive X chromosome, and XX women will have two copies of these genes expressed while XO women only have one copy expressed.
C) In XO women, the single X chromosome has no partner to pair with during mitosis so that each cell division is delayed by pairing problems with the single X not finding a pairing partner.
D) XO women have two copies of the SRY gene so that they are forced to develop partway along the male pathway during embryogenesis.
E) None of these are reasonable explanations.
