Representatives of the two Amblycoryphini genera examined in this study, Paraplangia and Orophus, have a karyotype including 31 (male) or 32 (female) acrocentric chromosomes with X0 (male) and XX (female).
A Robertsonian translocation occurs due to the breakage of two acrocentric chromosomes (numbers 13, 14, 15, 21 and 22) or near the centromeres, with the subsequent fusion of their long arms (14,15).
The karyotype with FN=68 is composed by six pairs of biarmed and 22 acrocentric chromosomes.
The number of metaphase chromosomes in all cells was 60 normal acrocentric chromosomes (Figure 4).
Changes in chromosome morphology without apparent variation in GTG-banding patterns were observed between the metacentric AMO 5 and the acrocentric NLA 1 and also between the metacentric AMO 9 and the acrocentric NLA 9.

Karyotype (2n= 54, XY) with 17 pairs of acrocentric and nine pairs of metacentric/submetacentric chromosomes, and an acrocentric heteromorphic sexual pair (Oliveira et al., 2012a).
The other pairs are subtelocentric or acrocentric. The chromosome pairs are the most prominent characteristics at the karyotype of the genus Fritillaria.
