Heredity of integrations of Trypanosoma cruzi kDNA minicircles into several loci of the chicken genome. Rows A, B, and C show integrations into the macrochromosomes, into the intermediate chromosomes, and into the microchromosomes, respectively. The numbers in parentheses indicate the total numbers of times that an insertion (red bar) was present at a chromosomal locus from animal source.
