Meiotic behavior of small chromosomes in maize. [PDF]
Front Plant Sci, 2013 The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine, and then separate at anaphase I. At anaphase II, sister chromatids separate. However, studies of small chromosomes in maize derived from a variety of sources typically have failure of sister chromatid cohesion at anaphase I.

Mysterious meiotic behavior of autopolyploid and allopolyploid maize. [PDF]
Comp Cytogenet, 2018 This study was aimed to investigate the stability of chromosomes during meiosis in autopolyploid and allopolyploid maize, as well as to determine an association of chromosomes between maize (Zeamaysssp.mays Linnaeus, 1753) andZ.perennis(Hitchcock, 1922) Reeves & Mangelsdor, 1942, by producing a series of autopolyploid and allopolyploid maize ...

Multiple roles of Spo11 in meiotic chromosome behavior [PDF]
EMBO Journal, 2000 Spo11, a type II topoisomerase, is likely to be required universally for initiation of meiotic recombination. However, a dichotomy exists between budding yeast and the animals Caenorhabditis elegans and Drosophila melanogaster with respect to additional roles of Spo11 in meiosis.

Reciprocal translocations: tracing their meiotic behavior [PDF]
Genetics in Medicine, 2008 Segregation and interchromosomal effect studies have been performed in reciprocal translocation carriers by sperm-fluorescent in situ hybridization reporting a great heterogeneity. The divergences have been attributed to the particular cytogenetic characteristics of each rearrangement.

Complex chromosomal rearrangements: origin and meiotic behavior [PDF]
Human Reproduction Update, 2011 Complex chromosomal rearrangements (CCRs) describe structural rearrangements, essentially translocations, involving at least three breakpoints on two or more chromosomes. Although they are rare in humans, their clinical identification is important since CCR carriers can display various phenotypes which include phenotypically normal subjects, infertile ...

MEIOTIC BEHAVIOR OF ASYMMETRIC DYADS IN THE MALE DROSOPHILA [PDF]
Genetics, 1973 ABSTRACT Crossing over in the interstitial region of the heterozygous V4 translocation in Drosophila melanogaster generates asymmetric dyads each consisting of a shorter and a longer chromatid It was shown previously that in the female the shorter is recovered preferentially (ZIMMERING 1955); the present work suggests that the same ...

Meiotic behavior of Brachiaria decumbens hybrids
Genetics and Molecular Research, 2015 Brachiaria decumbens is a forage grass of inestimable value for livestock in Brazil due to its production of good quality forage even when planted on acid and poor soils, although it is susceptible to pasture spittlebugs. Only one cultivar, cv. Basilisk, has been used as the pollen donor in crosses with Brachiaria ruziziensis since 1988 at Embrapa Gado

The meiotic behavior of an inversion in Caenorhabditis elegans. [PDF]
Genetics, 1992 Abstract The rearrangement hIn1(I) was isolated as a crossover suppressor for the right end of linkage group (LG) I. By inducing genetic markers on this crossover suppressor and establishing the gene order in the homozygote, hIn1(I) was demonstrated to be the first genetically proven inversion in Caenorhabditis elegans.

The Development and Meiotic Behavior of Asymmetrical Isochromosomes in Wheat [PDF]
Genetics, 1997 To determine which segments of a chromosome arm are responsible for the initiation of chiasmate pairing in meiosis, a series of novel isochromosomes was developed in hexaploid wheat (Triticum aestivum L.). These isochromosomes are deficient for different terminal segments in the two arms.
