  • Each line represents the observed cell lineage for B.a(l/r)aa (aa) and B.a(l/r)pp (pp) from one male animal. Other B cell progeny developed normally in all animals. For wild type, the number of progeny from each cell type is indicated in parentheses. Abnormal cell lineages are indicated by underscoring.

  • a Genotype: lin-48(sy234); him-5(e1490).

  • b abn-n indicates that the cell lineage was abnormal, but produced n progeny.

  • c τ indicates the cell produced the normal pattern of progeny, but cell division axes were abnormal.

  • d (l) and (r) indicate that the cells failed to migrate to their normal anterior/posterior positions. One cell (l) remained on the left, and one cell (r) remained on the right.

  • e Genotype: lin-49(sy238); him-5(e1490).

  • f γ* is a commonly observed abnormal lineage (Chamberlin and Sternberg 1993). It results in four progeny instead of the normal six.
