Fig 2. Fitness distribution patterns of identified Mendelian traits within large natural population.
Comparisons of the fitness distribution on 6 selected conditions in individual crosses (left panel, N=40) and across ~1000 natural isolates of S. cerevisiae (right panel, N=960) are shown. Conditions tested are color-coded. (A) Bimodal distribution patterns observed both in crosses and at the population level. (B) Bimodal distributions observed only in crosses but not within a population.
