Chimpanzee chromosome 12 is homologous to human chromosome arm 2q
Cytogenetic and Genome Research, 1978Most of the 46 human chromosomes find their counterparts in the 48 chimpanzee chromosomes except for chromosome 2 which has been hypothesized to have been derived from a centric fusion of two chimpanzee acrocentric chromosomes. These two chromosomes correspond to the human chromosomes 2p and 2g.

TaASY1 promotes homologous chromosome interactions and is affected by deletion of Ph1.
The Plant Journal, 2009During meiosis, chromosomes are sorted into homologous pairs as a preface to their intimate association via recombination and synapsis. However, little is known about the mechanism used to distinguish homologous chromosomes from other chromosomes present

On determining the parental origins of homologous chromosomes
Annals of Human Genetics, 1981SUMMARYGiven sets of measurements on a pair of homologous chromosomes from an individual and both his/her parents, methods for estimating the probability that the individual has inherited any particular two of the four parental homologues are discussed and compared. A new method with several desirable properties is proposed.

Initiation of homologous chromosome pairing during meiosis.
Biochemical Society Transactions, 2006Following pre-meiotic DNA replication, homologous chromosomes must be paired and become tightly linked to ensure reductional segregation during meiosis I. Therefore initiation of homologous chromosome pairing is vital for meiosis to proceed correctly.

Pairing of homologous chromosomes as phase transition
SPIE Proceedings, 2007In some cells pairing of homologous chromosomes happens at particular moments during the cell life cycle. A Statistical Mechanics model based on some experimental data is presented and discussed here for this phenomenon. Under this model, chromosomes pair at special regions whose interaction is mediated by some molecules which diffuse in cells ...

Chromosome banding homologies in Swamp and Murrah buffalo
Journal of Heredity, 1981Silver staining of Swamp buffalo (2n = 48) metaphase chromosomes revealed telomeric nucleolus organizer regions (NOR's) located on five pairs of autosomes identified by R-banding as numbers 4 p (submetacentric), 8, 20, 22, and 23 (acrocentrics); interphase nuclei also showed no more than five nucleoli.

“Homologies” between non-homologous chromosomes in the grasshopper Caledia captiva
Chromosoma, 1978Cytological studies of hybrids between three chromosomal forms of the grasshopper, Caledia captiva, have revealed a clear case of pairing and exchange between non-homologous chromosomes. The genomes of each of the three chromosomal forms are readily identifiable by their marked differences in morphology and in the pattern of C-heterochromatin ...

Rearrangement of human cell homologous chromosome domains in response to ionizing radiation.
International Journal of Radiation Biology, 1997Chromosomes are located within the interphase nucleus in regions called domains. Using fluorescence in situ hybridization with whole chromosome paints, a pain of homologous chromosomes can be visualized as two discrete domains and their relative spatial ...

Do homologous chromosomes differ?
Cytogenetic and Genome Research, 1973Two statistics are derived for testing whether measurements on otherwise indistinguishable chromosome pairs differ. The power of these tests is shown as well as a method for estimating the true homolog means. The tests and estimation procedures are simple to compute, and their use is illustrated on chromosome data.

Simulation of chromosomal homology searching in meiotic pairing
Journal of Theoretical Biology, 1995A cellular automaton model has been developed to simulate some aspects of chromosome behaviour during meiotic prophase when homologous chromosomes search for each other so that they can pair. Simulations allow one to compare the relative efficiencies of random searching by chromosome shuffling along the inner nuclear membrane or within the lumen of the
