Model Organism Lab - A microscopic view of 24-48 hour zebrafish embryos Model Organism Lab - A microscopic view of a roller nematode worm, which has a mutation in a gene responsible for proper cuticle formation Model Organism Lab - A microscopic view of a wildtype nematode worm Model Organism Lab - A microscopic view of wildtype and dumpy nematode worms (C. elegans) Model Organism Lab - A microscopic view of zebrafish embryos, which are widely used in genetic study Model Organism Lab - A student holds up a BST mouse, which displays a kinked tail, a white spot on its belly, white feet, and ocular defects Model Organism Lab - A student holds up an Obese mouse, which has a predisposition to diabetes, cold intolerance, depressed immune function, and infertility Model Organism Lab - A student observes the African Clawed Frog, which is important for its oocytes (eggs) Model Organism Lab - A view of a Pirouette mouse, which displays circling, head tilting, and deafness Model Organism Lab - A view of a Snell's Dwarf mouse with its wildtype littermate Model Organism Lab - A view of an Obese mouse with its wildtype littermate Model Organism Lab - A view of the African Clawed Frog Model Organism Lab - An Obese mouse, which is deficient in the leptin signaling pathway Model Organism Lab - Don't drop the frog! Model Organism Lab - Snell's Dwarf mice are much smaller than their wildtype littermates, are sterile, and are deaf (all due to deficiency in hormones) Model Organism Lab - The Pirouette mouse has defects in the peripheral vestibular system and abnormal development of sensory cells in the inner ear Model Organism Lab - The students are fascinated by the Pirouette mouse Model Organism Lab - The students discuss the importance of model organisms in genetic research Model Organism Lab - The students look at nematode worms and zebrafish embryos under the microscope Model Organism Lab - The students observe VGSC-Beta1 mice, which have seizures and die by 21 days Model Organism Lab - The students observe mice that serve as an animal model for multiple sclerosis
