non-homologous chromosomes

A spontaneous somatic exchange between non-homologous chromosomes in Drosophila melanogaster.

It should not be confused with chromosomal translocation, which is rearrangement of parts between non-homologous chromosomes.

'Non-homologous chromosomes' representing all the biological features of an organism form a set, and the number of sets in a cell is called ploidy.

A recent study of the S. cerevisiae Sgs1p gene suggests that it removes or prevents ectopic recombination events between non-homologous chromosomes [ 44].

A Robertsonian translocation is a type of nonreciprocal translocation involving two homologous (paired) chromosomes or non-homologous chromosomes (i.e. two different chromosomes, not belonging to a homologous pair).
