a-m877527 - a putative Cy-regulated unstable allele

A newly arisen unstable a allele has been confirmed. This allele arose as a single kernel exception. The pattern of mutability is of a late medium-fine quality, our classification 7-b (Reddy and Peterson, MGG, 1983). As evident in the tabulation, there is a high frequency of spotting, indicative of many regulatory elements or autonomous control of mutability.
