The Relationship between Genetic Recombination and Commitment to Chromosomal Segregation at Meiosis

Abstract

When meiocytes are removed from a meiosis-inducing environment at an early stage of development they can revert to mitotic division. At later developmental stages, however, they exhibit an irreversible commitment to the completion of meiosis and lose the ability to return to mitosis (Stern and Hotta, 1969; Ganesan et al., 1958; Simchen et al., 1972).
