Introduction. In the past two decades, there has been a wealth of research highlighting the robust lifespan- and healthspan-extending effects of dietary restriction (DR) [1–3], defined as a reduction in nutrient intake without malnutrition.Much of this work has been directed towards the trade-off between reproduction and survival that typically occurs as …

SpletIsogamous species often have two mating types. Some isogamous species have more than two mating types, but the number is usually lower than ten. In some extremely rare cases a species can have thousands of mating types. In all cases, fertilization occurs when gametes of two different mating types fuse to form a zygote.
