WebJul 29, 2012 · Presentation Transcript. Chromosomal Aberrations • Can be caused either by • non-disjunction (failure of whole chromosomes to separate during meiosis) • translocation (bits of chromosomes that are re-attached to other chromosomes). Individuals end up either with extra whole or bits of chromosomes or with missingwhole or bits of chromosomes. WebSpherical Aberration. For lenses made with spherical surfaces, rays which are parallel to the optic axis but at different distances from the optic axis fail to converge to the same point. For a single lens, spherical aberration can be minimized by bending the lens into its best form. For multiple lenses, spherical aberrations can be canceled by ...
