WebApr 3, 2024 · Owing to stochastic fluctuations arising from finite population size, known as genetic drift, the ability of a population to explore a rugged fitness landscape depends on its size. ... This article is part of the theme issue ‘Interdisciplinary approaches to predicting evolutionary biology’. WebAug 18, 2024 · How do you calculate your fitness score? The normal range is from 18 to 25. For example: If your weight is 70.5kg and your height is 1.82 meters, first obtain square of your height – multiply your height by itself 1.82 x 1.82 = 3.3. Then, divide your weight by this figure 70.5 / 3.31 = 21.3.
