Summary Introduction
To determine: Whether natural selection at any level of organization ever causes extinction of a population or species.
Introduction: Natural selection is a natural phenomenon in which the organism adapts certain characters that are beneficial for the survival. These changes are incorporated in the genetic material and are then passed on from one generation to the other. It is called natural selection because the organism selects certain characters and then makes changes in the genotype. Natural selection is one of the reasons for evolution.

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.
