Abstract
A study of 23 asci showing aberrant segregation for ascospore color revealed that some mechanism other than crossing over, back mutation, or irregularities in nuclear survival is responsible for their occurrence. It is believed that they have resulted from transreplication, by which a locus is copied more than the normal number of times during replication at meiotic prophase. The occurrence of 53 ratios in some asci lends confirmation to the hypothesis that each chromatid is composed of 2 functional subunits.This publication has 2 references indexed in Scilit:
