GENETIC-VARIABILITY IN THE GERMAN-COCKROACH (DICTYOPTERA, BLATTELLIDAE) - ADDITIONS TO 2 LINKAGE GROUPS, INCLUDING EFFECTS OF TRANSLOCATIONS ON RECOMBINATION

The inheritance and linkage of 2 new mutants, white eye (w) and blotch (Bh), are described. White eye is a simple autosomal recessive. It is allocated to linkage group IV (chromosome 7) on basis of linkage with orange body and T(7;12)/7;12. Bh is allocated to linkage group XI bec ause of linkage with fused antenna (Ss), and with T(7;12)/7;12 and T(3 ;12)/3;12. In linkage tests of w? and Bh with translocations involving chromosome 12, recombination in males was much lower than in females. In females, recombination agreed closely with linkage estimates that did not involve translocation heterozygotes.
