Litoria spenceri Northern Site x Central Site: captive bred tadpole

One unsexed mixed Northern and Central Site tadpole was studied. Thirty-one of 33 spreads counted were 2n = 26. Nine karyotypes were prepared, confirming the 2n = 26 karyotype ( Fig. 8; data not shown). When arranged in descending order of size, the same chromosomal metacentric, submetacentric, and subtelocentric configuration was observed as for the Central Site animals ( Figs. 4, 8; Table 1; data not shown). DAPI negative regions were evident on the short arms of both homologous chromosomes of chromosome 9, and one chromosome 11 matched chromosome in all nine karyotypes ( Figs. 4, 8; data not shown). The one matched chromosome of the chromosome 11 pair that did not display this DAPI negative region was submetacentric in all nine karyotypes ( Figs. 4, 8; data not shown).
