> Some (many) may suspect that the genome is all one needs, I don't think that is generally accepted. The genome can be seen as a bunch of data (raw bits), you must add context to transform that into usefull information. When a living thing reproduces that context is readily available: the parent(s). Often something must be transferred that is not part of the genome, like for instance intesinal bacteria. And genome is not a clear cut definition: is mitochndrial DNA part of the human genome or not? And after the succesfull hatching you sometimes need to inject some more information to raise the product to something 'usefull'. In the case of humans this often .
