A high degree of polymorphism for the length and copy number of rDNA spacers, in both the X and Y chromosome clusters, has been found in a wild population of Drosophila melanogaster. The genetic behaviour of rDNA structural variants in separate and mixed populations derived from isofemale lines suggests that they are not subject to strong selection and are stable for over 1,000 generations. The high structural variability suggests an evolutionary rapid process of turnover in the family which… 
Inheritance of the rDNA spacer in D. melanogaster
TLDR
The r DNA loci segregated with a Mendelian pattern; interhomologous recombination events occurred at the expected rate; conversely unequal crossing-over within the rDNA locus appears not to be as frequent as expected.
Reciprocal recombination and the evolution of the ribosomal gene family of Drosophila melanogaster.
TLDR
The data indicate that reciprocal recombination alone cannot be responsible for the observed variation in natural populations, and this region is a hotspot for heterochromatic recombination.
Multigene family of ribosomal DNA in Drosophila melanogaster reveals contrasting patterns of homogenization for IGS and ITS spacer regions. A possible mechanism to resolve this paradox.
TLDR
A single-stranded exchange mechanism is proposed to resolve the paradox of a relatively fast rate of X-Y and X-X interchromosomal exchanges of IGS length variants in agreement with a multilineage model of homogenization.
Paradoxes of Molecular Coevolution in the rDNA Multigene Family
TLDR
This work describes paradoxes of molecular coevolution in the rDNA for which there are no clear-cut solutions as to why and how they became established.
Monitoring the Mode and Tempo of Concerted Evolution in the Drosophila melanogaster rDNA Locus
TLDR
Variation in locus size and retrotransposon load was correlated with large changes in the number of uninserted and R1- inserted units, yet the numbers of R2-inserted units were relatively unchanged.
Molecular drive: a cohesive mode of species evolution
TLDR
There are circumstances in which the unusual concerted pattern of fixation permits the establishment of biological novelty and species discontinuities in a manner not predicted by the classical genetics of natural selection and genetic drift.
Evidence for biased gene conversion in concerted evolution of ribosomal DNA.
TLDR
Concerted evolution of rDNA in parthenogenetic lizards of hybrid origin is strongly biased toward one of two parental sequences, which is consistent with biased gene conversion as the operative mechanism.
Gene duplication and concerted evolution of the GPDH locus in natural populations of Drosophila melanogaster
TLDR
The sn-glycerol-3-phosphate dehydrogenase locus of Drosophila melanogaster is polymorphic with respect to the number of tandemly duplicated genes in natural populations, and the observed polymorphism is driven mainly by random genetic drift.

Similarities and differences in the structure of X and Y chromosome rRNA genes of Drosophila
TLDR
Examination of the structure of X and Y rDNAs with restriction endonucleases reveals that the X rDNA contains repeating units not present in the Y, illustrating difficulties with the hypothesis that recombination is the predominant mechanism preserving similarities between these two clusters maintained on different chromosomes.
Arrangements and rearrangements of sequences flanking the two types of rDNA insertion in D. melanogaster
TLDR
The two types of Drosophila melanogaster rDNA insertion occur at different sites in the 28S gene, separated by 51 nucleotide pairs, and type I insertion elements in tandem arrays are flanked by very short segments of the28S rRNA gene.
Molecular evidence for genetic exchanges among ribosomal genes on nonhomologous chromosomes in man and apes.
We have found that human and ape ribosomal genes undergo concerted evolution involving genetic exchanges among nucleolus organizers on nonhomologous chromosomes. This conclusion is based upon
Characterization of cloned ribosomal DNA from Drosophila hydei.
TLDR
The structure of ribosomal genes from the fly Drosophila hydei has been analyzed and structural similarities in that both contain repeated sequence elements of similar size and location are shown.
Unequal crossing over at the rRNA tandon as a source of quantitative genetic variation in Drosophila.
TLDR
It is argued that the bb alleles arose by unequal crossing over in the rRNA tandon and are shown to occur, and the minimum estimate of the rate of occurrence of changes at the r RNA tandom is 3 X 10(-4).
