Chromosomal distribution of GACA (A) and GATA (B) repeats across the six eukaryotes based on in-silico analysis. The repeat density of the GACA/GATA tetramers across the chromosomes sets in different species is expressed in base-pairs per megabase of each chromosome. Note the differential occurrence of these repeats along different chromosomes. The human and dog genomes were found to be GATA rich. The GATA repeats were predominant on the human and chicken Y chromosomes. Status of these repeats on the Y chromosomes in other species remained unclear due to their unfinished genomes.
