We used the haplodiploid spider mite Tetranychus urticae Koch to test for inbreeding depression and purging. Four pivotal life-history traits of this herbivore were examined: maturity rate ...

Haplodiploid organisms (diploid females and haploid males) are genetically distinct in that they have asymmetrical genetic segregation, gene dosage compensation in the haploid male, maternal ...

The role of genetic factors in extinction is firmly established for diploid organisms, but haplodiploids have been considered immune to genetic load impacts because deleterious alleles are readily ...

Researchers at University of Tsukuba investigated secondary contact zones, hybridization, and genetic introgression in two closely related species of spider mites, haplodiploid organisms found at ...

In these species, the genetic structure of kinship among individuals changes fundamentally due to the haplodiploid nature of males. In a scenario where the queen has mated only once with a male, the ...

1) Sex ratio theory has assumed that females can produce offspring of both sexes. It has been suggested that some females in haplodiploid populations are only able to produce sons (constrained sex ...

Scientists have found a female bee that had two fathers and no mother in the first documented case of its kind. Honeybees are known as haplodiploid. This is a system of sex determination—females ...

“Haplodiploid animals are expected to add further insight to this evolutionary story. But few studies have examined whether this is the case—this is what we investigated.” ...

Whether an insect will have a male or female offspring depends on the weather, according to a new study. As in bees, wasps, and ants, the gender determination of Trichogramma parasitoids is called ...
