All of these cultures are descendents of 4 of Mrs. Lindegren's cultures, 11911, 11914, 2154, 8456 and the cytochrome-(glycerine)
deficient mutant of 8456, 8456-w-1. Except for these four cultures, for c[ . . . ]ch I've given Mrs. Lindegren's determination
of the genotype, the genotype of the various segregants is given only when the culture has been tested for those characters.
The pedigrees were copied from very rough notes -- so they're rough too -- the designations for cytochrome may be confusing
-- "c" is the glycineless mutant, with a faint c band if any, and C the normal. Cultures 25.1, 108.31 D and 108.3
P-2 are cytoplasmic petites, genetically C. 108.3 N is normal with respect to cytochrome, 108.3 Pink A -- is an adenine-deficient
pink mutant of 108.3. 54.2 LA is a normal back mutant of the originally mutant segregant 54.2 (c) and apparently the same
allele as in the normal parent and the rest of these pedigrees. Cultures are normal for cytochrome unless otherwise indicated.
