chromosome pairing

chro·mo·some pair·ing

(krō'mō-sōm pār'ing),
The process in synapsis whereby homologous chromosomes align opposite each other before disjoining in the formation of the daughter cell; the apposition permits exchange of genetic material in crossing-over.

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.

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).
