HOMOLOGOUS CHROMOSOME [2 records]

Record 1 2013-11-15

English

Subject field(s)
  • Genetics
DEF

Any two chromosomes that undergo pairing during the prophase of meiosis. They are very similar in length and shape, have centromeres at the same point, and contain the same gene loci. They occur in all diploid organisms and their presence infers that two copies of each gene occur in each cell, although these copies may differ in being allelic forms of the same sequence.

French

Domaine(s)
  • Génétique
OBS

Qualifie chacun des deux chromosomes d'une même paire dans une cellule diploïde.

OBS

Quand il s'agit de gènes, on parle de préférence de gènes allèles car la notion d'allélisme est plus complexe, en particulier dans les cas de polyallélie.
