Diploidy and dominance in artificial genetic search

Complex Syst., 1992
It has been theorized that in natural genetics, diploidy and dominance inrease the survivability of species in environments that vary with time. This paper examines the effects of diploid representations and dominance operators in genetic algorithms applied to non-stationary search problems.

GENETIC EVIDENCE FOR DIPLOIDY IN EQUISETUM

American Journal of Botany, 1986
Sporophytes and gametophytes of Equisetum arvense, E. laevigatum, and E. telmateia were analyzed using enzyme electrophoresis to estimate isozyme number. Despite their uniformly high chromosome numbers (2n = 216), these three species exhibited isozyme numbers typical of diploid seed plants for the enzymes AAT, ADH, ALD, GDH, [NADP]IDH, LAP, MDH, [NADP ...

Parasite diversity and the evolution of diploidy, multicellularity and anisogamy

Journal of Theoretical Biology, 1990
It may be reasonably assumed that a diversity of parasite genotypes in any one cell or organism is more harmful than a population of uniform genotypes. If this is accepted the following consequences follow: (i) Parasite mixing, due to cytoplasm mixing, at the time of zygote formation is a new and additional cost of sex.

Independent origins of diploidy in Metarhizium.

Mycologia, 2018
In fungi, stable diploid genome arrangements are rare. Here we present evidence from nuclear intergenic DNA sequencing, microsatellite genotyping, and configuration of the mating-type locus to demonstrate two independent origins of persistent diploid genome organization in the Metarhizium majus species complex.

Polygenic inheritance — A haploid scheme that can outperform diploidy

1998
Nonstationary function optimisation has proved a difficult area for Genetic Algorithms. Standard haploid populations find it difficult to track a moving target and tend to converge to a local optimum that appears early in a run. While it is generally accepted that various approaches involving diploidy can cope better with these kinds of problems, none ...
