Insertion frequencies of full-length, solo and fragmented LTR elements along the chromosome 10. DNA density for chromosomal arms and pericentromeric regions was calculated from the total DNA of three contigs (~10.4 cM and ~62.8 cM in arms, ~10.5 cM in pericentromeric regions) on Chromosome 10 (see Methods). Both copia-like and gypsy-like LTR retrotransposons exhibit nonrandom clustering along the chromosome. More LTR retrotransposons reside in the pericentric regions of the chromosome than in the arms, and short arm of Chromosome 10 also displays a higher density of the elements than long arm. The number of gypsy-like elements are more than that of copia-like elements on chromosome 10.
