Abstract

Heterozygotes for three long inversions on chromosome 1 were analyzed by serial reconstruction from electron micrographs. Measurements of loop lengths at different meiotic prophase substages revealed that the homologous synapsis of the inverted region was gradually replaced by nonhomologous synapsis as loops were eliminated during pachytene. This synaptic adjustment was apparently not affected by crossovers which occurred within the 150- and 160-cM long loops.
