(a) Giemsa-stained karyotype of a male specimen of E. virescens (2n=38XX:XY). Chromosome pairs were ordered by size. Pair 15 is sex determining. The heterochromatic block of the X chromosome is shown in the inset (bottom right). (b) Fluorescence in situ hybridization of a Y chromosome probe on a male metaphase of E. sp.2 showing the homology of a large metacentric to two acrocentric chromosomes. (c) Schematic representation of the sex chromosomes in E. sp.2 males and females.
