The changes in cardiac function that might be expected after surgical replacement of a defective heart valve. Introduction: The heart is the most important organ of the circulatory system. It is a muscular organ that pumps oxygenated blood to every part of the body. It consists of four valves namely mitral valve, tricuspid valve, aortic valve, and pulmonary valve. The total amount of blood that the heart pumps through the circulatory system in a minute is referred as cardiac output. It is mainly determined by two factors: the heart rate and stroke volume.

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
