Table 1.
Number of different genes in chromosomes (and their ratio relative to the total) of different lengths, sum over the whole population.
Values are an average over 200,000 time steps starting at t = 2∙106. Parameters are: D = 3, S = 21, μ = 10−3, νlinkage = νbreak = νrecomb = 0.01.
Fig 1.
Semi-log plot of the frequency of different templates with no chromosome breakage or recombination.
Frequencies are normalized on gene count (i.e., a chromosome with 3 genes counts as three when measuring the frequency), parameter values indicated at the top of the figure. Chromosomes consisting of 3∙n (n is positive integer) genes are plotted as thick lines.
Fig 2.
Frequency of different templates with chromosome break and recombination.
Frequencies are normalized on gene count, parameter values indicated at the top of the figure (standard parameter set). Chromosomes consisting of 3·n (n positive integer) genes are plotted as thick lines. (Chromosomes with a frequency less than 1% are not shown).
Fig 3.
The equilibrium fitness of the population as a function of the split size (S) at two different numbers of essential genes D = 3 and D = 5.
Average of 10 independent runs. Relevant parameters as in Fig 2 (μ = 10−3, νlinkage = νbreak = νrecomb = 0.01).
Fig 4.
Average number of genes in chromosomes as a function of gene number (D) and split size (S) with break and recombination.
Parameters are μ = 10−3νlinkage = νbreak = νrecomb = 0.01. The area enclosed in black lines shows the viable region without chromosomatization.
