Polymorphism in the rates of meiotic drive acting on the B-chromosome of Myrmeleotettix maculatus

Shaw, MWH, G. M.; Anderson, D. A.,  Heredity,  55:61-68. 1985.

A survey of all the available data on meiotic transmission rates in M. maculatus suggests that a polymorphism in female transmission rate exists in most natural populations. Differences in the frequency of the types or in the transmission rates they manifest may exist between populations or over time, but the evidence is not compelling. The data on males are also equivocal, especially because the environment may affect male transmission rate. We suggest that the polymorphism in female rates may demonstrate the selective equilibrium between the B and the genome in which it exists.
