I. Allozymic and activity variation [Elektronische Daten] [Darrell Yardley, Rema Gapusan, Jack Jones, Buddy Hughes] Amylase allozymic and activity variation was studied in three flocks of chickens (Gallus domesticus). Individuals from one flock were studied to assess the effects of sex, tissue, and genotype on amylase activity. Additionally, the allozymes were purified and their specific activities compared. Variation was observed within and among the flocks. Two alleles were found to be segregating in the flocks, one flock being polymorphic and the other two monomorphic. Mean amylase activities among the three flocks were significantly different. The relationship of this activity variation to regulatory variation is discussed. There were no significant effects of sex or genotype on amylase activity and, in most cases, no correlation between activities in the various tissues. However, in heterozygotes one of the alloamylases had much lower activity than the other.
