Which statement is true? coronary veins are the blood vessels that bring oxygenated blood from the heart muscle to the right atrium of the heart. blood pumps through the aorta and into smaller blood vessels to supply the cells of the body with oxygen. the left coronary artery moves oxygenated blood into the muscle of the right side of the heart. systolic blood pressure is a measurement taken when the heart is at rest and refilling with blood.

Two true-breeding pea plants were crossed. one parent is round, terminal, violet, constricted, while the other expresses the respective contrasting phenotypes of wrinkled, axial, white, full. the four pairs of contrasting traits are controlled by four genes, each located on a separate chromosome. in the f1 only round, axial, violet, and full were expressed. in the f2, all possible combinations of these traits were expressed in ratios consistent with mendelian inheritance. (a) what conclusion about the inheritance of the traits can be drawn based on the f1 results? (b) in the f2 results, which phenotype appeared most frequently? what mathematical expression predicts the probability of occurrence of this phenotype? (c) which f2 phenotype is expected to occur least frequently? what mathematical expression predicts this probability? (d) in the f2 generation, how often is either of the p1 phenotypes likely to occur? express your answer as a fraction (example: 3/16).
