Crossingover in Terms of Meiosis

Duration: 33

Year Published: 1959

Creator: University Film Producers Assn

Format: 16mm

Color: B&W

Description: Presents the hypothesis that chiasmata represent physical evidence of crossingover. This would mean that crossingover takes place at a four-strand rather than a two-strand stage. Genetic proof for this is presented from studies with Neurospora, described in detail, and prefaced by a description of the life cycle and meiotic divisions of this organism. Discusses the normality of chiasmata, and hence crossingover, and pictures cytological evidence of crossingover. Lecture by Dr. G. W. Beadle.
