WebIn biology, fitness refers to an individual organism’s ability to successfully reproduce and submit their genes to the next generation of its species. Biological fitness can be measured in two different ways- absolute and relative. Absolute fitness is determined by the total amount of genes or offspring submitted to the next generation within ...
