WormBook, 2017 Sexual reproduction requires the production of haploid gametes (sperm and egg) with only one copy of each chromosome; fertilization then restores the diploid chromosome content in the next generation. This reduction in genetic content is accomplished during a specialized cell division called meiosis, in which two rounds of chromosome segregation follow

Journal of Experimental Botany, 2012 Meiosis is at the heart of Mendelian heredity. Recently, much progress has been made in the understanding of this process, in various organisms. In the last 15 years, the functional characterization of numerous genes involved in meiosis has dramatically deepened our knowledge of key events, including recombination, the cell cycle, and chromosome ...

Cell, 2001 Sexual reproduction predominates among eukaryotic organisms on our planet. While debate continues over why this should be so, burgeoning genomic and functional information now allows us to begin to think reasonably about some of the events that may have occurred to make sex possible in the first place.

Proceedings of the National Academy of Sciences, 1975 A four-factor cross between two strains of Phycomyces involving two auxotrophic, one color, and the mating type marker is described. Samples of 40 germspores from 84 individual fertile germsporangia were characterized. The results show: (i) The germspores of a germsporangium are derived from one meiosis in approximately 78% of the cases.

Hereditas, 2009 The present paper reviews our observations on the premeiotic DNA replication in Lilium and on the morphology and behaviour of chromosomes during the meiotic prophase in Schizophyllum, Lilium, Drosophila, Bombyx and Homo as revealed by three-dimensional reconstructions of synaptonemal complexes (SC).

BRCA2 in mammalian meiosis [PDF]
Trends in Cell Biology, 2022 Breast cancer type 2 susceptibility protein (BRCA2) is a central regulator of homologous recombination in somatic cells and safeguards genomic integrity against DNA double-strand breaks (DSBs). Recent evidence suggests that association with unique meiosis-specific cofactors allows BRCA2 to facilitate homologous recombination in germ cells.

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]
, 2020 In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]
, 2011 During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

Homolog pairing during meiosis : dyneins on the move [PDF]
, 2010 Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.
