The falciform ligament in the adult, which carries the round ligament of the liver in its free border, is the remnant of ventral mesogastrium that conveyed the umbilical vein from the umbilicus to the liver in the foetus.

feedback1="'''Incorrect.''' The mesonephric duct drains the embryological form of the kidney, the mesonephros. In the male it develops into the Wolffian duct which develops into the epididymis, vas deferens and seminal vesicles. In females the mesonephric duct regresses.

feedback4="'''Correct!''' Gonadal differentiation is determined by the presence of the SRY gene of the Y chromosome (sex determining region of the Y chromosome) which encodes testicular determining factor protein (TDF). Lack of SRY gene (i.e. XX females) leads to ovarian differentiation. [[Reproductive Embryology Development - Pathology|WikiVet Article: Genital development]]"
