1. Investigation of polymorphisms of myogenic factors and myostatin genes as molecular markers for quantitative traits in Gallus gallus. / Investigação de polimorfismos nos genes dos fatores Miogênicos e Miostatina como marcadores moleculares para características quantitativas em Gallus gallus.
The aim of this work was to identify polymorphisms in five candidate genes (MyoD, Myf5, Myogenin, MRF4 and Myostatin) which act in chicken muscle development and evaluate the effects of its allelic variants on growth and muscle development quantitative traits. MyoD and Myf5 are essential for the determination of the myogenic lineage of muscle precursor cells

2. Population Genetics of Drosophila Amylase. I. Genetic Control of Tissue-Specific Expression in D. PSEUDOOBSCURA
Drosophila pseudoobscura is polymorphic for tissue-specific expression of α-amylase in adult midguts. This enzyme is encoded by a single locus, Amy, on the third chromosome. In this paper we show: (1) Up to about 12 days post-eclosion, the midgut activity patterns remain stable; after 12 days areas not showing activity previously begin to show activity. Thu
