If one parent has Type A blood and the other has type B, but all four types are represented among the offspring, what are the genotypes of the parents? If both parents are blood type A but ¾ of their children are type A and ¼ of the children are type O, what are the parent's genotypes?

What genotypes must the parents be if one has type AB blood and the other has type B, but their children are ¼ A, ¼ AB and ½ type B?

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
