In humans, dimples are dominant to not having them. If a heterozygous female mates with a male who is also heterozygous, what are the possible genotypes, phenotypes, and probabilities of this cross?

Answer and Explanation:

IMPORTANT NOTE: Due to technical problems, you will find the answer and the complete explanation in the attached file.

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.
