unequal crossing over

(Science: cell biology) crossing over between homologous chromosomes that are not precisely paired, resulting in nonreciprocal exchange of material and chromosomes of unequal length. Favoured in regions containing tandemly repeated sequences. A genetic defect occurring in crossing over where one of the homologous chromosomes receives more genetic information from the other chromosome than it passes over, therefore meaning that one of them has duplicated information while the other lacks the ex.
