haplodiploid

(hăp′lō-dĭp′loid′)
adj.
Of or relating to a system of sexual determination in which diploid females develop from fertilized eggs and haploid males develop from unfertilized eggs, as in most hymenopterans, such as ants and bees, and certain other invertebrates.
n.
A haplodiploid organism or species.

Complementary sex determination substantially increases extinction proneness of haplodiploid populations.
Haplodiploids have diploid females and haploid males.
Outbreeding depression, but no inbreeding depression in haplodiploid ambrosia beetles with regular sibling mating.
In hymenopteran insects (ants, wasps, bees), haplodiploid sex determination allows females to produce male and female offspring in variable proportions (Wilson, 1976; Thorahill and Alcock, 1983).
An additional bias is favored in haplodiploid species because inbreeding causes mothers to be more related to their daughters than their sons (Frank 1985; Herre 1985).
Haplodiploid and diploid models with sibling and parental control of the brood sex ratio and brood size.
pentagona, like all armored scale insects, is haplodiploid due to the elimination of the paternal chromosome set during development of the male eggs; males are haploid (N = 8) while females are diploid (N = 16) (Bennett and Brown 1958).
All this suggests the occurrence of diploid males is a normal occurrence in the haplodiploid system, but it remains a rare event (within the context of the life span of a species).
When one or both loci are sex-linked, or a haplodiploid sex determination system applies, then this method readily permits the use of data from both males and females in estimating the degree of disequilibrium.
The additional attributes of polyphagy and haplodiploid sex determination result in an ability of populations to develop insecticide resistance quickly (Reitz & Funderburk 2012), and invasive populations largely were resistant to broad-spectrum insecticides before they became invasive (Immaraju et al.
