Explanation

A. Heterozygous refers to having two different alleles for a gene, one inherited from each parent.

B. Recessive refers to an allele that only expresses its trait if two copies are present (homozygous), but this term does not describe the inheritance pattern itself.

C. Dominant refers to an allele that expresses its trait even if only one copy is present, but again, this term does not describe the inheritance pattern.

D. Homozygous describes a gene when the same allele is inherited from both parents (e.g., AA or aa).

Correct Answer is B

Explanation

A. Aortic valve regurgitation: This condition involves the backward flow of blood from the aorta into the left ventricle, not the left atrium.

B. Mitral valve regurgitation occurs when the mitral valve does not close properly, allowing blood to flow back from the left ventricle into the left atrium during systole.

C. Mitral valve stenosis involves the narrowing of the mitral valve, restricting blood flow from the left atrium to the left ventricle, but does not involve backflow into the left atrium.

D. Aortic valve stenosis is the narrowing of the aortic valve, which restricts blood flow from the left ventricle into the aorta, not back into the atrium.
