There are “greedy alleles”, they code for an endonuclease that causes a double-strand break and inserts itself into the genome. I suspect that preventing lethal overwhelming of the genome by such things is why eukaryotes have limited DNA replication fidelity. It isn’t a bug, it is a feature that prevents selfish DNA from selfishly replicating itself.

Potential links to “my king/Party/Country right or wrong” ?

Anyone know where this definition comes from, as I do not recall? This is not the same as crude reproductive success; total number of offspring produced.

And frequently there must be a napkin.
