Meiotic abnormalities in metaphase I human spermatocytes from infertile males: frequencies, chromosomes involved, and the relationships with polymorphic karyotype and seminal parameters [PDF]
Asian Journal of Andrology, 2014 The aim of this study was to look in depth at the relationship between meiotic anomalies and male infertility, such as the determination of the chromosomes involved or the correlation with patient features.

Chromosome segregation and meiotic defects in carriers of chromosomal abnormalities
, 2009 Male carriers of chromosomal abnormalities (CA) are more frequent in the infertile population. These men have higher levels of sperm aneuploidy due to the aberrant segregation of the chromosomes involved in the abnormality. The presence of a CA may also influence the segregation of other chromosomes, in a process known as in interchromosomal effect ...

Folia Horticulturae, 2021 Pollen characteristics are very important for Iris interspecific hybridisation. In this study, the pollen viability and male meiosis were studied in yellow-flowered Iris dichotoma (Y2), I. domestica (S3) and their hybrids F1, F2 and BC1 (BC1-Y and BC1-S).

Evidence of Selection against Complex Mitotic-Origin Aneuploidy during Preimplantation Development. [PDF]
PLoS Genetics, 2015 Whole-chromosome imbalances affect over half of early human embryos and are the leading cause of pregnancy loss. While these errors frequently arise in oocyte meiosis, many such whole-chromosome abnormalities affecting cleavage-stage embryos are the ...

“Meiotic abnormality in dominant genic male sterile Brassica napus” [PDF]
Molecular Biology, 2008 Rs1046AB is a dominant genic male sterile (DGMS) Brassica napus line derived from Yi-3A. Until now the molecular mechanism of its male sterility is still unknown. In this paper, cytological observations demonstrated that all cells in sterile plants contained condensed nuclei at the beginning stage of meiosis; this implied that meiotic cells were ...

Effects of 5α-dihydrotestosterone and 17β-estradiol on the mouse ovarian follicle development and oocyte maturation. [PDF]
PLoS ONE, 2014 We have previously reported that androstenedione induces abnormalities of follicle development and oocyte maturation in the mouse ovary. In granulosa cells of the ovarian follicle, androstenedione is aromatized to 17β-estradiol (E2). To determine whether

Abnormal meiotic behavior in three species of Crotalaria [PDF]
Pesquisa Agropecuária Brasileira, 2009 The objective of this work was to compare the meiotic behavior and pollen grain viability of three species of Crotalaria. Slides for meiotic analysis were prepared by the air-drying technique. Pollen grain viability was measured by three staining procedures (Alexander's solution, tetrazolium chloride and fluorescein diacetate) and in vitro germination ...

On the origin of crossover interference : a chromosome oscillatory movement (COM) model [PDF]
, 2011 Background: It is now nearly a century since it was first discovered that crossovers between homologous parental chromosomes, originating at the Prophase stage of Meiosis I, are not randomly placed.

Kinesin-5 Eg5 is essential for spindle assembly and chromosome alignment of mouse spermatocytes
Cell Division, 2020 Background Microtubule organization is essential for bipolar spindle assembly and chromosome segregation, which contribute to genome stability. Kinesin-5 Eg5 is known to be a crucial regulator in centrosome separation and spindle assembly in mammalian ...
