On transmission of information by synapsis
International Journal of Bio-Medical Computing, 1970Abstract This study is a solution to a problem of information transmission by synapsis which is reduced to the integration of the equation with partial derivatives of the heat type with mixed conditions. The solution z(x, t) found is represented by an integral of Fourier series which tends to a singular integral in the neighbourhood of x = 0+, the

Synapsis and recombination in inversion heterozygotes
Biochemical Society Transactions, 2010Inversion heterozygotes are expected to suffer from reduced fertility and a high incidence of chromosomally unbalanced gametes due to recombination within the inverted region. Non-homologous synapsis of the inverted regions can prevent recombination there and diminish the deleterious effects of inversion heterozygosity.

Chromosome rotation and formation of synapsis
Nature, 1976ALTHOUGH the rotation and oscillation of the nuclei of cultured spermatocytes have been known for some years1,2, no correlations of this phenomenon with the stages of mitosis or meiosis, or with the biochemical or cytogenetic events during germ-cell development have been made.

Nature Genetics, 2005
The XY chromosome pair in mammalian males is sequestered into a transcriptionally dormant chromatin domain before the first meiotic division. New work shows that all chromosomes can suffer the same fate if they don't pair during meiosis, and that this may be part of a surveillance mechanism to protect against aneuploid gametes.

Science, 2005
The complex mechanics of the eukaryotic cell cycle is monitored at a number of points to ensure that everything is going according to plan before the next step in the process is executed. Known checkpoints include DNA replication, DNA damage, and spindle function. Bhalla and Dernburg identify a checkpoint that monitors synapsis, or pairing

Synapsis in a natural autotetraploid
Genome, 1999To test assumptions of the autotetraploid chromosome pairing model regarding events during synapsis, whole-mount spreads of synaptonemal complexes (SCs) of Machaeranthera pinnatifida (=Haplopappus spinulosus) (Asteraceae) (2n = 4x = 16) were analyzed by electron microscopy. On the assumption of one synaptic initiation per chromosome arm, each pachytene
