Eighty mutants in 17 ascospore character genes were studied for their conversion patterns. The correlation between conversion pattern and mutagenic origin, previously found in genes b1 and b2 was extended to all the genes studied. Aberrant 4:4 asci were found in most genes irrespective of their conv
## Pasadena strains of Ascobolus immersus were used to study the controls of gene conversion. Formulae were derived for estimating conversion parameters according to different hybrid DNA models of recombination. Genetic factors influencing conversion were determined by using genetically different
A fine structure map of gene b5 has been established in Ascobolus immersus and the unstable mutant site b5-301 (phenotype: ascospore coloration) has been found to map within this gene. This map was constructed using seven b5 mutants induced by ICR 170 and is based on the additivity of recombinant fr
