Record 1, Textual support, English
Record number: 1, Textual support number: 1 DEF
A recombinational event that involves recombining sites that are misaligned, and nonreciprocal recombinant chromosomes are formed as a result. 8, record 1, English, - unequal%20crossing%2Dover
Record number: 1, Textual support number: 1 CONT
Misalignment of homologous chromosomes during prophase I of meiosis can lead to unequal crossing over. Following an unequal crossing over event one of the resulting chromosomes will get an insertion and the other a deletion... Thus, unequal crossing over is a... mutation mechanism that causes insertions and deletions(in addition to replication slippage). Homologous chromosomes align due to sequence similarity, but misalignment may occur when the chromosomes carry non-homologous repeated sequences. 9, record 1, English, - unequal%20crossing%2Dover

Pendant plusieurs décennies, il fut accepté que seuls trois mécanismes pouvaient expliquer l'apparition de nouveaux gènes dans un génome. Le plus simple, et le premier identifié, consiste en la duplication d'un gène par enjambement inégal («unequal crossing-over»), qui produit deux copies filles à partir d'un gène préexistant [...] À l'origine identiques, ces copies accumulent au cours de l'évolution des mutations qui entraînent peu à peu la divergence des séquences des protéines codées. 3, record 1, French, - enjambement%20in%C3%A9gal
Record number: 1, Textual support number: 1 OBS
enjambement : Échange de segments d'ADN qui se produit au cours de la méiose entre deux chromosomes homologues ou au cours d'une mitose entre deux chromosomes homologues ou non. 4, record 1, French, - enjambement%20in%C3%A9gal
