Homologies between human and dolphin chromosomes detected by heterologous chromosome painting
Cytogenetic and Genome Research, 1998Human chromosome-specific probes for the entire karyotype were hybridized to metaphase spreads of the Atlantic bottlenose dolphin, <i>Tursiops truncatus, </i>to directly compare the evolutionary conservation of chromosomal segments between these two distantly related species.

“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 ...

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. A number of factors contribute to the initiation of homologous chromosome pairing including telomere ...

Homologous chromosome pairing: The physical problem
Journal of Genetics, 1942Homologous pairing of chromosomes is discussed in its physical aspects. The relevant facts about the cytology of pairing are examined, and the conditions stated which must be satisfied by any physical explanation. It is pointed out that these requirements are at first sight contradictory.

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.

[Homology of G-banded mammalian chromosomes].
Genetika, 1987Linkage relationships of homologous loci and high resolution G-banding patterns of man, mouse, rat, chinese hamster, rabbit, cat, mink, pig, ox and sheep were used for identification of 11 evolutionary conservative autosomal regions. The distributions and inversions of these regions in the ancestor genomes of some phylums have been shown.

Quantitative DNA variation and chromosome homology.
Symposia of the Society for Experimental Biology, 1986In many genera, of both plants and animals, divergence and speciation is often accompanied by massive changes in the amount of nuclear DNA. These changes, in turn, result from amplification or repetition of base sequences within the chromosomal DNA. The chromosomes of different species are consequently of different size and structure.
