- rolph 5y agowhen reproduction[X] occurs before a selective factor[y] is in play, the selective factor has no first order influence on reproductive success. the theory of inverse relationship between severity of symptoms and transmissibility, is based on the idea that sick individuals spend more time laying in convolesence than interacting with other individuals. this mechanism goes out the window when the infection is transmissible before symptoms appear. this is the case with covid, i wish it was other than wishfull hoping but it isnt.

- rolph 5y agocausing illness in the host after transmission allows more contact between infected and putative hosts thus conspecific differential of reproductive success. prospecific differential reproductive success occurs when variations are able to generate progeny that themlelves are capabe of reproducing. i.e. delta variant sars2 evolution occurs when the properties leading to these phenomenon are genetically based and transmitted through populations at varied frequencies subject to differential natural selection i.e. the fittest as in most apt to survive to reproductive modality.
