Pulmonary valve and Aortic valve
During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery.
<h3>What happen when ventricles contract ?</h3>
When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery
- Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.
- When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.

Option A will only give black fur, option B will only give white fur, and option C will only give black fur since parent 1 will only give the dominant B allele to the offspring. With Bb and Bb, the genotypes of the resulting offspring could be BB, Bb (which will result in black fur) or bb (which will result in white fur).
