A Short-Term Advantage for Syngamy in the Origin of Eukaryotic Sex: Effects of Cell Fusion on Cell Cycle Duration and Other Effects Related to the Duration of the Cell Cycle—Relationship between Cell Growth Curve and the Optimal Size of the Species, and Circadian Cell Cycle in Photosynthetic Unicellular Organisms

Percentage of anisogamous fusions (between different age classes) according to the instantaneous death rate and the instantaneous probability of fusion in a discrete analysis with ten age classes. The higher the percentage of anisogamous fusions, the more advantages for syngamy.
