Dear Joshua:

Thank you for your note of January 27 indicating that you are
using our tryptophan data to figure out recombination; I am very glad
that you are doing this, Unfortunately, through transduction, linkages
can be detected only between markers that are located in the same seg-
ment; and, since this occurs very rarely when dealing with unrelated
genes, we do not have many opportunities to figure out linkages and
use your formula, In fact, so far, the linkage between the try loci
and cysB is the only case we have in which unrelated markers are close
together,

From your letter I understand that you are preparing a mono-
graphic review on Recombination, In case you have not already
arranged for publication of this review, we would be very much inter-
ested in having it appear in Advances in Genetics. The material for
the next volume is just being prepared now; and if we could get the
manuscript within a month it would come out very promptly.

 

I am looking forward to seeing you in Glasgow and London. With
best regards,

Sincerely yours,

MD:af M, Demerec
