Confirmation of the linkage between Tp1 and sl1

--Scott Poethig

Tp1 has never been mapped relative to its closest neighbor, sl , in crosses involving both of these loci. Three point linkage data between Tp1, gl1 and sl1 indicate that sl1 is 3.2cM distal to Tp1 (Table 1). These data confirm the location of these loci on the current genetic map.

Table 1. + Tp1 +/gl1 + sl1 x gl1 + sl1
 
a) + Tp1 + 104
gl1 + sl1 81
b) gl1 Tp1 + 10
+ + sl1 13
c) + Tp1 sl1  6
gl1 + + 1
   
Total progeny: 215

% recombination
gl1--Tp1: (b) = 10.7 ± 2.1 %
gl1--sl1: (b + c) = 14.0 ± 2.4 %
Tp1--sl1: (c) = 3.2 ± 1.2 %
