A statistical Approach to the Study of Pollen Fitness
- 657 Downloads
The theory of evolution based on natural selection assumes that individuals of a population differ with regard to adaptability to the environment where the population lives. As a consequence the contribution of each individual to the progeny generation, in terms of progeny size, differs. This contribution is referred to as fitness, and is expressed in a quantitative manner relative to a standard individual, generally the fittest of the population. Accordingly, fitness is a quantity varying from zero to one. The component characters producing this variability are: viability, reproductive ability and fertility.
