Another recording of excision to a closely linked site

--Peter A. Peterson

There have been numerous reports and authentications of transposons transposing to linked sites. Notably, the case with P-VV, a-m(Au), a-m(papu), bz-m etc. This is another case. This one from the a2-m55064 allele that reverted to A2-Rev. This A2-Rev was crossed to a2-m(r) and backcrossed by a2 bt. The following progeny types were observed:
 
Cld. cls. spt. Total % spt. Exchange
106 86 12 204 5.8 + 12%

In this one case, the En transposed 12cM from A2.
