Abstract
Chromosome size, number and types are some of the degrees of freedom exploited by evolution in the variation of eukaryotic organism complexity and this can be seen to have increased over time in some lineages. This chapter explores the effects of fitness landscape ruggedness upon various aspects of chromosomes drawing upon the results in Chap. 4: the effects of varying the number of chromosomes in a sexual diploid are explored using versions of the NK model. Results suggest that landscape ruggedness, chromosome length, and the initial function of the chromosome copy, can all affect evolution. The effects of sex determination chromosomes and hence mating types is also explored within the model, with the XY (ZW) and X0 (Z0) systems shown to be beneficial under certain conditions due to the ruggedness of the fitness landscape.
