Karyotype analysis results of mapped gene-containing fosmid clones: PF126M18 (A); PF123H24 (B); PF109F4 (G); PF106B20 (D); PF118H7 (E); PF123J11 (F); PF120E14 (G). Chromosome numbering is based on chromosome type and relative length. Wherein, chromosome pair 1, 2, 3 represent the metacentric (m) chromosomes. Chromosome pair 4, 5, 6, 7, 8 represent the submetacentric (sm) chromosomes. Chromosome pair 9, 10, 11, 12, 13, 14, 15, 16 represent the subtelocentric (st) chromosomes. Chromosome pair 17, 18, 19 represent the telocentric (t) chromosomes.
