WebFor example, in one of Mendel's pea plant experiments, the alleles were purple (PP) and white (pp). Alleles are usually either dominant or r ec essive. Dominant alleles only need one copy to show up in an individual. In this case, the dominant allele is purple (P). ... In biology, fitness refers to the reproductive success of an individual ... Fitness is often defined as a propensity or probability, rather than the actual number of offspring.

Thus the phrase ’expected number of offspring’ means the average number, not the number produced by some one individual.
