Meiotic behavior of small chromosomes in maize [PDF]
Frontiers in Plant Science, 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.

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 ...

Using wheat-rye 1BL.1RS translocations to disclose the effects of subtelomeric tandem repeats on meiotic behavior of homologues [PDF]
BMC Plant BiologyBackground The subtelomeric region of the 1RS arm of rye (Secale cereale L.) contains several kinds of tandem repeats with high copy number and they can affect meiotic recognition and pairing of this chromosome arm.

The Impact of Open Pollination on the Structural Evolutionary Dynamics, Meiotic Behavior, and Fertility of Resynthesized Allotetraploid Brassica napus L. [PDF]
G3: Genes, Genomes, Genetics, 2017 Allopolyploidy, which results from the merger and duplication of two divergent genomes, has played a major role in the evolution and diversification of flowering plants.

Meiotic behavior of several Brazilian soybean varieties [PDF]
Genetics and Molecular Biology, 2000 Despite the importance of soybeans little cytogenetic work has traditionally been done, due to the small size and apparent similarity of the chromosomes. Fifteen soybean [Glycine max (L.) Merrill] varieties adapted for cultivation in two distinct regions

Abnormal meiotic behavior in three species of Crotalaria Comportamento meiótico anormal em três espécies de 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.

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 ...

Passiflora cristalina and Passiflora miniata: meiotic characterization of two wild species for use in breeding [PDF]
Crop Breeding and Applied Biotechnology, 2017 Passiflora cristalina and Passiflora miniata are two new wild species found in the southern Amazon region. This study aimed to analyze the meiotic behavior of the two species, by meiotic analysis, meiotic index and pollen grain viability, using routine ...
