Abstract:Summary Sexual crosses were studied between mutants ofPhycomyces blakesleeanus with abnormal phototropism (phenotypemad). Recombination frequencies were determined among five genesmadA tomadE. No clear evidence was found for linkage between any of the genes. Inconsistent results in crosses involvingmadC are attributed to nonisogenicity between the particular strains used. Onemad strain was discovered to be a double mutant. A new gene, tentatively designatedmadG, was segregated from a cross involving that strain.
