The probability of having a daughter is 50%.
The genotype of both parents is AO. The chance of having a child with an OO genotype is therefore 0.25
The probability of having a daughter who has the OO genotype and therefore blood group O is thus 0.5 × 0.25 = 0.125.

Question: Select the correct statement about the special fetal blood vessels.
A The umbilical vein becomes the ligamentum teres.
B The distal parts of the umbilical arteries form the superior vesical arteries.
C The hepatic portal vein forms from the umbilical artery.
D The fossa ovalis becomes the f
oramen ovale.
Answer:
C) The umbilical vein becomes the ligamentum teres.
Explanation:
After birth, many vascular changes occur in the newborn child as the pulmonary, renal and digestive systems start functioning. As the umbilical cord is tied off and severed, the blood does not flow through the umbilical arteries. The umbilical vein in the child collapses but remains as the ligamentum teres. Ligamentum teres is a round ligament and serves to attach the umbilicus to the liver. It is present in the free border of the falciform ligament of the liver.
