There Are Three Robo Genes (Robo, Robo2, and Robo3) Encoding

Question 3

Essay

There are three Robo genes (Robo, Robo2, and Robo3) encoding receptors for Slit, which acts as a midline repellant. In homozygous Slit mutant embryos, all axons collapse at the midline, while in homozygous Robo mutant embryos, axons re-cross the midline, resulting in thinner longitudinal tracts and thicker commissures (Figure Q7-8). There are three Robo genes (Robo, Robo2, and Robo3) encoding receptors for Slit, which acts as a midline repellant. In homozygous Slit mutant embryos, all axons collapse at the midline, while in homozygous Robo mutant embryos, axons re-cross the midline, resulting in thinner longitudinal tracts and thicker commissures (Figure Q7-8). Figure Q7-8 What would you expect the ventral nerve cord phenotype of a triple Robo mutant (loss of function of all three Robo genes) to be? Briefly explain your reasoning. Figure Q7-8
