Complex mechanisms regulate gene dosage throughout eukaryotic life cycles. Mechanisms controlling gene dosage have been extensively studied in animals, however it is unknown how generalizable these mechanisms are to diverse eukaryotes.

Haploidy and aneuploidy in switchgrass mediated by misexpression of CENH3
Cross bred species such as switchgrass may benefit from advantageous breeding strategies requiring inbred lines. Doubled haploid production methods offer several ways that these lines can be produced that often involve uniparental genome elimination as ...

Haploidy in somatic cells is induced by mature oocytes in mice
Yeonmi Lee, Aysha Trout, Nuria Marti-Guiterrez et al. examine different aspects of somatic cell haploidization in mouse enucleated oocytes. Their results provide further insight into generating oocytes carrying somatic genomes.

Haploidy of somatic cells in mouse oocyte using somatic cell nuclear transfer
Haploidization in somatic cells is the process of reducing the diploid somatic chromosomes to haploid. Several studies have attempted somatic haploidization using oocytes in mice and humans.

The prospects for using haploinducers in maize breeding
The discovery of spontaneous haploid plants and the development of ways to produce them in in vitro culture have set a new direction important for breeding and for theoretical research in reproductive biology.

Haploidy in early bovine embryos produced in vitro [PDF]
Early bovine embryos (two - to sixteen blastomeres) produced in vitro were cytogenetically analysed to determine the incidence of haploidy. Follicular oocytes were matured in vitro and inseminated with sperm prepared using the swim up method.

ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

ABSTRACT Doubled‐haploid (DH) technology based on in vivo haploid induction has become an effective strategy for accelerating maize breeding. However, improving haploid inducer populations remains challenging because accurate estimation of haploid induction rate (HIR) requires labour‐intensive phenotypic validation, while putative HIR estimates are ...

Haploid Induction in Tomato (Solanum lycopersicum L.) via Gynogenesis
The generation of new hybrid varieties of tomato (Solanum lycopersicum L.) is the most widely used breeding method for this species and requires at least seven self-fertilization cycles to generate stable parent lines. The development of doubled haploids

Advanced eusociality, kin selection and male haploidy
The generation-long primacy of kin selection in explaining the evolution of advanced eusociality in social insects has been challenged in recent papers. Does this challenge succeed?
