In molecular cytogenetics, GISH efficiency is applied to visualize homoeologous chromosome pairing
during meiosis, parental genome assortment, and genome recombination .
studies has disclosed the progenitors of C.
Observations of the chromosome pairing
of meiosis were made and documented with an Olympus BX-51 microscope coupled with a Photometric SenSys CCD camera.
In this case, sex chromosomes and autosomal polymorphisms should not be in genetic equilibrium and there should be differences in the extent of chromosome pairing
and morphologies of chromocenters when putative parental and combinational types are compared.
The effect of telome ric heterochromatin on chromosome pairing
of hexaploid triticale.
diversicolor supertexta marker chromosomes, (2) chromosome pairing
, (3) the number of chromosomes of each type, and (4) the ratio between the total length of metacentric chromosomes and submetacentric chromosomes.
Light and electron microscope studies of chromosome pairing
in relation to chiasma localisation in Stethophyma grossum (Orthoptera: Acrididae).
Researchers examine recent developments in three primary areas: quantitative genetic methods for analysis of homologous recombination and chromosome pairing
, development of direct physical assays for DNA intermediates and products of recombination, and cytological techniques for characterizing chromosome behaviors and the patters with which specific proteins associate with meiotic chromosomes.
Patterns of meiotic chromosome pairing
were compared between three sunflower plants: cultivated sunflower (Helianthus annuus L.
Aegilops speltoides chromosomes can induce or promote meiotic chromosome pairing
and the consequent genetic recombination between related chromosomes from different genomes (homeologous chromosomes) in hybrids with tetraploid and hexaploid wheats.
Hence, chromosome pairing
has been shown to be under genetic control and is also influenced by environmental conditions.
Such modalities of chromosome pairing
were also found in humans (Gosden el al., 1976; Luciani et al., 1978).
