The isolation of En-1 in the wx-84-4 allele

En was isolated from an unstable wx allele, identified as wx-84-4. This arose out of a population cross of C-I Sh Bz Wx; En, En x C sh bz wx. wx-84 -4 was one of 12 wx alleles isolated but two appeared to have instability. Because only two were isolated from two different populations, only those values will be presented.

wx-84-4 - 1 in 1.9 X 10-6 = En-1
wx-84-11 - 1 in 3.9 x 10-5

This is a conservative estimate because the other 11 have not been verified for instability or wx confirmation.
