Biological Evolution and Statistical Physics
Here, we develop a more general formulation of the quasispecies equations that is applicable to diploid and even polyploid genomes.
Semiconservative quasispecies equations for polysomic genomes: The general case
However, in contrast to the haploid case, we have found that an analytical solution for the mean fitness is considerably more difficult to obtain for the polyploid case.
Semiconservative quasispecies equations for polysomic genomes: The general case
In contrast to previous work , the quasispecies equations developed here are not restricted to haploid genomes, but rather may applied to diploid and even polyploid genomes.
Semiconservative quasispecies equations for polysomic genomes: The general case
It simply means that obtaining an analytical expression for the mean fitness is considerably more difficult for the polyploid case than it is for the haploid case.
