Characterization Of Sine Oculis, Eyes Absent And Dachshund Mutant Phenotypes And The Search For Novel Regulators, Loralyn Cozy

The complexity of the Drosophila compound eye is under the control of eight “master control” genes. These genes are known to interact genetically and biochemically. Documentation of various gene expressions in various eye gene mutants is reported here as well as preliminary results from a deficiency screen to find novel regulators of the eye gene dachshund. Interestingly, in addition to the varying effects of eye genes on one another, we report alternate functions for which sine oculis, eyes absent and dachshund are critical such as gut formation and nervous system development. We also propose slight modifications to the current …

Science By Accident: Poems Inspired By Science, Ambert Stover

I have had so many biology and other science classes that I automatically think about the world in scientific terms. Once I found a slug while I was building a trail and gleefully announced to my trail-building companion that terrestrial gastropods were hermaphroditic. To me it meant that the slug I had found was simultaneously both male and female. To my friend, however, it was utter gibberish. This is what I call “science by accident.” Not that it’s a bad thing—penicillin was discovered by accident! But I do have to be mindful of who I am talking with and which …

Reinforcement theory is a controversial mechanism by which speciation can occur through reduced hybrid fitness promoting the evolution of reproductive isolating mechanisms. Populations within a hybrid zone may be at differing relative abundances which may affect their risk of hybridization and strength of sexual isolation. The effect of relative abundance has been seldom examined in studies of reinforcement. Chrysochus cobaltinus and C. auratus leaf beetles from a zone of secondary contact in central Washington were run in various multi-choice mating trials to determine if lab results were indicative of those occurring in nature and whether relative abundance had an effect …
