Metaphase karyotypes from larval neuroblast cells. a, b An. maculatus Java strain: a Giemsa stain showing a long acrocentric X chromosome, a small telocentric Y chromosome and autosomes II and III and b diagrammatic representation. c, d An. maculatus Thailand strain: c large submetacentric X3 and Y2 chromosomes and autosomes II and III and d diagrammatic representation. Only one set of autosomes II and III is present. Variable heterochromatic portions are indicated in black. The centromeres are indicated by constrictions of each chromosome. Chromosome lengths, arm ratios and heterochromatic parts are shown in proportion
