Q. In a natural population of out breeding plants, the variation of the total number of seeds per plant is 16. From natural population, 20 plants are taken into the laboratory and developed into divide 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 5.8 across all sets. Approximate the broad-sense heritability for seed number in this population. H^2 = (16-5.8)/16 = 0.64 is this right?
