Fig. 8. Karyotype from a Northern Site x Central Site L. spenceri unsexed tadpole hybrid. A representative karyotype demonstrates the L. spenceri 2n in The critically endangered species Litoria spenceri demonstrates subpopulation karyotype diversity

Fig. 8. Karyotype from a Northern Site x Central Site L. spenceri unsexed tadpole hybrid. A representative karyotype demonstrates the L. spenceri 2n = 26 karyotype and DAPI negative areas in the long arm of chromosome 9, as well as one matched chromosome of chromosome 11. The chromosome 11 matched chromosome that does not contain the DAPI negative area is submetacentric.

Fig. 4. Chromosomes 9 and 11 from different L. spenceri populations. Three representative chromosomes from each animal demonstrate a highly conserved DAPI negative region in the long arms of chromosome 9. A DAPI negative region is observed in the long arm of chromosome 11, but only in the Central Site juveniles and in only one matched chromosome of the Northern Site x Central Site tadpole hybrid. Arrows indicate the chromosome 11 DAPI negative region. Asterisks indicate the paired submetacentric chromosome 11 matched pair of the Northern Site x Central Site tadpole hybrid.
