Bead theory

From Wikipedia, the free encyclopedia

The bead theory is a disproved hypothesis that genes are arranged on the chromosome like beads on a necklace. According to this theory, the existence of a gene as a unit of inheritance is recognized through its mutant alleles. Seymour Benzer showed in the 1950s that the bead theory was not correct.
