Flow cytometry of normal and abnormal pig karyotypes. Preliminary report.

Flow cytometry technique was applied to normal pig chromosomes and to three different reciprocal translocations: trcp (4q-; 14p), trcp (3p+;7q-) and trcp (1q-;15q+). The rearranged chromosomes generate new peaks which seem to correspond to their relative lengths. Therefore, it is necessary to confirm these results by banding analysis and/or by hybridization on these chromosomes with probes of genes known to be localized on them.
