Describe the flow of blood from the umbilical vein to the descending aorta in the developing fetus.
n200080 [17]

Oxygen and nutrients from the mother's blood are transferred across the placenta to the fetus through the umbilical cord. This enriched blood flows through the umbilical vein toward the baby's liver. There it moves through a shunt called the ductus venosus. This allows some of the blood to go to the liver.

A small amount of the blood continues on to the lungs. Most of this blood is shunted through the ductus arteriosus to the descending aorta. This blood then enters the umbilical arteries and flows into the placenta. The oxygen rich blood then returns to the fetus via the third vessel in the umbilical cord (umbilical vein). The oxygen rich blood that enters the fetus passes through the fetal liver and enters the right side of the heart.

An independent array of genes has to have different chromosomes or to be sufficiently far on the same chromosome to allow for crossing. The associated genes are in the same chromosome and have no overlap. Together they are transferred to the daughter cells.
