A Computational Approach to Estimating Nondisjunction Frequency in Saccharomyces cerevisiae. [PDF]

, 2016
Errors segregating homologous chromosomes during meiosis result in aneuploid gametes and are the largest contributing factor to birth defects and spontaneous abortions in humans.

Determinants of Chromosome Architecture: Insulator Pairing in cis and in trans

PLoS Genetics, 2016
The chromosomes of multicellular animals are organized into a series of topologically independent looped domains. This domain organization is critical for the proper utilization and propagation of the genetic information encoded by the chromosome.

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]

, 2006
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and

Identification of 5P Chromosomes in Wheat-Agropyron cristatum Addition Line and Analysis of Its Effect on Homologous Pairing of Wheat Chromosomes

Frontiers in Plant Science, 2022
As an important wheat wild relative, the P genome of Agropyron cristatum (L.) Gaertn. (2n = 4x = 28) is very valuable for wheat improvement. A complete set of wheat-A.

Protein-mediated chromosome pairing of repetitive arrays. [PDF]

J Mol Biol, 2014
Chromosomally integrated arrays of lacO and tetO operator sites visualized by LacI and TetR repressor proteins fused with GFP (green fluorescent protein) (or other fluorescent proteins) are widely used to monitor the behavior of chromosomal loci in various systems.

Agent-based modeling of nuclear chromosome ensembles identifies determinants of homolog pairing during meiosis.

PLoS Computational Biology
During meiosis, pairing of homologous chromosomes (homologs) ensures the formation of haploid gametes from diploid precursor cells, a prerequisite for sexual reproduction.

Multiple opposing constraints govern chromosome interactions during meiosis.

PLoS Genetics, 2013
Homolog pairing and crossing over during meiosis I prophase is required for accurate chromosome segregation to form euploid gametes. The repair of Spo11-induced double-strand breaks (DSB) using a homologous chromosome template is a major driver of ...

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

, 1984
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

Surviving a Genome Collision: Genomic Signatures of Allopolyploidization in the Recent Crop Species [PDF]

, 2017
Polyploidization has played a major role in crop plant evolution, leading to advantageous traits that have been selected by humans. Here, we describe restructuring patterns in the genome of Brassica napus L., a recent allopolyploid species.

Meiosis: Checking Chromosomes Pair up Properly [PDF]

Current Biology, 2006
Faithful recombination and chromosome segregation in meiosis require regulated steps of homolog recognition and association which are monitored by meiotic checkpoints. A recent study in the nematode Caenorhabditis elegans has identified a checkpoint mechanism that monitors chromosome pairing during meiosis.
