How to make a haploid male

It is found that inbreeding does not pose an obvious evolutionary barrier, on account of a previously neglected sex‐ratio effect whereby the production of haploid sons leads to an abundance of granddaughters that is advantageous in the context of inbreeding.

Conditions for the invasion of male‐haploidy in diploid populations

Two theories, the maternal transmission hypothesis (MTH) and the deleterious mutation hypothesis (DMH), are re‐investigated with an agent‐based model to understand the role of genetic drift as a mechanism facilitating the spread of male‐haploidy.

What haplodiploids can teach us about hybridization and speciation

A theoretical model to compare the rate of nuclear and mitochondrial introgression in haplodiploid and diploid species shows that when two haplodiPloid species hybridize, nuclear genes are much less likely to cross the species barrier than if both species were to be diploids.

Patterns of reproductive isolation in a haplodiploid mite, Amphitetranychus viennensis: prezygotic isolation, hybrid inviability and hybrid sterility

Variations and asymmetries in the degree of reproductive isolation highlight the importance of reinforcement of prezygotic reproductive isolation through incompatibility and the important of cytonuclear interactions for reproductive isolation in haplodiploid spider mites.

Sexual antagonism in haplodiploids

A series of evolutionary-genetic models of sexual antagonism for haplodiploids are developed, incorporating details of their molecular biology and social ecology, and it is found that PGE promotes female-beneficial alleles more than arrhenotoky.

Intragenomic conflict under paternal genome elimination

It is established for the first time that both head and body lice reproduce through paternal genome elimination (PGE), an unusual genetic system in which males transmit only their maternally derived chromosomes.

The unusual reproductive system of head and body lice (Pediculus humanus)

It is established for the first time that both head and body lice reproduce through paternal genome elimination (PGE), an unusual genetic system in which males transmit only their maternally derived chromosomes.

The evolutionary dynamics of haplodiploidy: Genome architecture and haploid viability

It is found that low chromosome number evolved prior to haplodiploidy, and that it is unlikely that diplodiploidsy has reevolved from haplodi ploid lineages of mites, consistent with the predicted importance of haploid male viability.

Common endosymbionts affect host fitness and sex allocation via egg size provisioning

Cardinium augmented female production by increasing maternal fitness and egg size, thereby boosting fertilization rate and offspring fitness and Wolbachia reduced the beneficial effects of Cardinium, demonstrating different invasion strategies and antagonistic effects of endosymbiotic bacteria on host fitness and evolution of sex allocation.



Evolution of paternal care in diploid and haplodiploid populations

It is found that haplodiploidy may either inhibit or promote paternal care depending on model assumptions, but that under the most plausible scenarios it promotes – rather than inhibits – paternal care.

Sex determination in the hymenoptera.

Sex determination in the model hymenopteran Nasonia vitripennis does not involve CSD, but it is consistent with a form of genomic imprinting in which activation of the female developmental pathway requires paternally derived genes.

Male genes with nowhere to hide; sexual conflict in haplodiploids

The main conclusions are that the opportunity for between-locus sexual conflict should be the same for haplodiploids as for diploids, provided that the sexually antagonistic alleles involved are sex-limited from when they first appear.

Haplodiploidy, Sex-Ratio Adjustment, and Eusociality

Hamilton’s “haplodiploidy hypothesis” holds that inflated sororal relatedness has promoted altruistic sib rearing in haplodiploids, potentially explaining their apparent predisposition to

It is concluded that haplo‐diploidy not only facilitates the evolution of sister‐sister altruism by kin selection but also facilitates the Evolution of maternal care and female‐biased sex ratios, two prerequisites for eusociality.

Sexual conflict, sex allocation and the genetic system

This work considers how biased gene transmission, as expressed in different genetic systems, enhances the opportunity for sex ratio conflict and gives empirical examples that confirm that males and females have the opportunity to influence sex ratios.

A review of the literature in general shows relatively low inbreeding depressed in haplodiploid species, but indicates that inbreeding depression can be as high as that found in Drosophila.

Unmatedness Promotes the Evolution of Helping More in Diplodiploids than in Haplodiploids

It is shown that in haplodiploids, unmatedness promotes helping in females but not in males within the empirical range, and in diplodi Ploidiploids, the effect is stronger than in Haplodiploid, all else being equal.

Inbreeding depression and purging in a haplodiploid: gender-related effects

The hypothesis that, in haplodiploids inbreeding effects and genetic variation due to deleterious recessive alleles may depend on gender is supported.
