Additional linkage data for a\325, nd, yg\282, and yg\333.<p>

Burdick, A.  B.<p>
     
The following a\325 linkage data are mainly taken from the a\325 F2 segregates
in trans-phase.  The a\325 - nd data are from cis-phase.<p>

The following are two sets of trans-phase yg\282 - nd F2 data that show a
consistent linkage effect of around 41% C.O. If this is so, it will put yg\282
on chromosome 10 because nd has shown only 10% recombination with H (TGC8:10).<p>

      + +   +yg\282   nd +     nd yg\282       % C.O.

</pre>

The following trans-phase F2 data for yg\333 indicate about 38% C.O.  with al
but it might be well for E. A. Kerr to caeck this with gf or the trisomic
before assigning yg\333 to chromosome 8.<p>
