Independent Segregation

Year Published: 1959

Description: Demonstrates independent segregation by different pairs of genes using Mendel's data. Emphasizes the chromosomal activities during meiosis which are responsible for independent segregation. Describes the Punnett Square and the branching track methods of combining gametes at random. Discusses test crosses and linkage (as the exception to independent segregation), and shows that independent segregation proves the separability of the germ plasm into many gene pairs. Depicts the role of genetic recombination in speeding the process of evolution. Lecture by Dr. E. Altenburg.
