Abstract
The segregation of achiasmate chromosome pairs at meiosis I is not bro ught about by a single 'distributive system' as previously thought, bu t rather by two separate mechanisms. One system uses the pairing of pr oximal heterochromatic sequences to mediate the segregation of achiasm ate homologs - an observation that, at long last, defines a function f or heterochromatin. The other system facilitates the segregation of he terologous chromosomes, by an as yet undiscovered mechanism.
