Cytogenetic analysis of the T(X;5) translocation strain of Ceratitis capitata. DAPI-stained mitotic chromosomes were obtained from the brains of wild-type larvae (a, b) and T(X;5) larvae (c–f). X and Y symbols denote sex chromosomes, symbol 5 stands for chromosome 5. Bar = 10 µm. (a) Female mitotic prometaphase with two X chromosomes and five pairs of somatically paired autosomes. (b) Female mitotic metaphase with two X chromosomes and five pairs of autosomes. (c) Female mitotic prometaphase showing reciprocal translocations between two X chromosomes (asterisks) and two somatically paired chromosomes 5 (arrows). (d) Female mitotic metaphase showing reciprocal translocations between two X chromosomes (asterisks) and two chromosomes 5 (arrows). (e) Male mitotic prometaphase showing a T(X;5) translocation on the X chromosome (asterisk) and a large T(5;X) translocation on one chromosome 5 (arrowhead). Note that the somatically paired homologue of chromosome 5 and the unpaired Y chromosome appear normal. (f) Male mitotic metaphase showing a T(X;5) translocation on the X chromosome (asterisk) and a large T(5;X) translocation on one chromosome 5 (arrowhead). Note that the homologue of chromosome 5 and the Y chromosome appear normal.
