a-m877515
- a likely a-rcy allele with
a low mutability pattern
--Peter A. Peterson
The mutability occurs in the absence of
En, and Cy is implicated. This is based on the absence of
En in 10/10 cases of a mutability and the presence of Cy
in 6/6 cases of a mutability. A reconstruction test has not been
completed. The mutability pattern is a very low type (very late, infrequent
spots). This is surprising because in an associated test, this same Cy
gives a very strong effect (the standard high frequency, late spots) on
bz-rcy. This would indicate that the receptor elements are responding
differently to the same Cy, either because of a size difference
or a positional alteration.
