dc.description.abstract | Several new models are proposed for the evolution of haplodiploidy. Each of these models is evaluated for its ability to explain (1) special problems associated with transition to haplodiploidy from a population of diplodiploid progenitors, (2) current patterns of population structure in haplodiploid and related species, and (3) the evolution of genetic systems similar but not identical to haplodiploid systems. Of the new models, three are based on special conditions associated with inbreeding. Close inbreeding provides for the automatic effects of reduced problems in expressing recessives, lowered differences in gain from heterozygosity (to produce both heterotic effects and a greater variety of offspring) between haploid and diploid males, effective protection of haploids from direct competition with diploids, and a mechanism for the spread of haplodiploidy through gains derived from increased ability to control sex ratio. These models differ in the context where gain from sex ratio control is expressed. Pathways for the evolution of haplodiploidy in outbreeding populations are also discussed. Females who parthenogenetically produce haploid males have high genetic relatedness to their sons. If the sperm of these males is used to make both sons and daughters, i.e., through matings with diplodiploid females, there may be a net gain for haplodiploids. Another outbreeding model, modified from S. W. Brown (1964, Genetics 49, 797-817), deals with selection for females producing haploid males in populations where there are driving sex chromosomes. Biases created by drive in sex ratio may allow haplodiploid females to be the only effective producers of males in the population. Several of the new models explain the whole range of haplodiploid and related adaptations and provide predictions that appear to be more consistent with the known structure of contemporary populations than those available in current models. | en_US |
