Abstract

Formation of an adult organism from a single fertilized cell is the result of selective differential gene expression, operating on a constant pool of genetic information. The differential gene action can be viewed by the differential synthesis and activity of certain enzymes. The variation patterns in two enzyme systems of alpha and beta esterases have been studied in a univoltine race 1-380, bivoltine NB,D, and in a trimoulter race of silkworm Bombyx mori L. In total, 10 different development stages of each of the races were analysed. The number of bands and their intensity varied during different developmental stages indicating differential gene action. The pattern of variation of enzyme bands and their significance are herein discussed.
