No. It is an accidental condition that sometimes occurs during early pregnancy.
Molar pregnancy. Molar pregnancy is not a traditionally inherited disorder. A partial mole develops at either at conception (2 sperm fertilize 1 egg) or immediately after conception (1 sperm enters an egg and duplicates). A complete mole forms similarly but with an empty egg.
Usually not. Molar pregnancy happens ususally in young or older women who are pregnant but an ingerited defect is not present usuallly.
