Statistical analysis of cryptic variation inDrosophila alcohol dehydrogenase

Proceedings: Animal Sciences 09/1981; 90(5):545-552. DOI: 10.1007/BF03186034

ABSTRACT

Statistical analysis indicated that mean alcohol dehydrogenase (ADH) activity levels within ADH1 and ADH11 isochromosomal lines varied significantly among the Mexican populations ofDrosophila melanogaster used. Also as indicated by coefficient of variation values for ADH activity, the relative amount of genetic variation differed
among and within the ADH1 and ADH11 strains examined. The quantitative nature of the differences in ADH activity supported the concept of the additive gene action
of the alcohol dehydrogenase (Adh) locus. The manner in which our isochromosomal lines were constructed suggested that genes regulating ADH activity inD. melanogaster were located on the second chromosomes.
