✦ Synopsis


Two translocationcarrying stocks of mice, T(7; I5)9H and Rb(4;lS) were resistant to chemical leukemogenesis by 7,1Z-dimethylbenz(a)-anthracene (DMBA) or methylnitroso-Nurea (MNU). Lymphomas were induced in F, hybrids derived from crossing these two stocks with various susceptible strains. In T-cell leukemias originating from F, hybrids with Rb(4;lS) as one parent and strain CBA or ASW as the other, the translocation chromosome

## Abstract Trisomy of chromosome 15 is a highly regular feature of murine T‐cell leukemogenesis. We have studied the chromosomal constitution of 7,12‐dimethylbenz(__a__)anthracene (DMBA)‐induced T‐cell leukemias in C57BL × CBAT6T6 F, mice. The CBAT6T6‐derived chromosome 1(14:15)6 was regularly dup

## Abstract Four combinations of translocation heterozygotes with cytogenetically distinct chromosomes 15 were used to investigate whether the T‐cell leukemia‐associated duplication of chromosome 15 is a non‐random or a random event. In leukemias of AKR X CBAT6T6 F~1~ (Group I) and C57BL X CBAT6T6
