Abstract excerpt
Analysis of manifestation and inheritance of a new mutation inducing irregular synapsis in rye showed that abnormal phenotype is determined by a recessive allele of the sy19 gene. In the homozygotes for this mutation, even at the light microscopic level, abnormal formation of bivalents is already observed at pachytene-diakinesis. At metaphase I, the univalent frequency varies from 0 to 14; in a few cells,...
