      Reference

      Mutant for female meiotic segregation: 10.0% X chromosome exceptions from X/Bal females. 60% 4th chromosome exceptions from X/Bal females. Primarily affects achiasmate chromosome segregation. Causes high levels of X missegregation and extremely high levels of 4 missegregation. There is a large excess of diplo-4 ova over nullo-4 ova.
