Comparative cytogenetic map of macrochromosomes of the Chinese soft-shelled turtle (<i>Pelodiscus sinensis</i>).

<p>Homologous chicken and human chromosomes are shown to the left of each turtle chromosome (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053027#pone.0053027.s006" target="_blank">Table S1</a>). Genetic linkages that are homologous to chicken macrochromosomal arms and/or macrochromosomes (GGA1p, 1q, 2p, 2q, 3, 4q, and GGA5–8) are represented by 10 differently colored bars, and segments drawn with diagonal lines indicate the chicken Z chromosome. The G-banded ideograms of the turtle chromosomes, which were constructed using Hoechst 33258-stained band patterns obtained by the replication banding method, were taken from our previous report <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053027#pone.0053027-Matsuda1" target="_blank">[37]</a>. Solid bars to the right of the turtle chromosomes indicate the chromosomal segments in which intrachromosomal rearrangements occurred that resulted in differences between the turtle and chicken chromosomes.
