  • Numbers of base pairs included in the deletions that caused the frameshift mutations are indicated in parentheses. Note that grau shows two different splice forms, with RT–PCR bands of similar intensities, on the neo-Y lineage (see supplemental Figure S1 at http://www.genetics.org/supplemental/).

  • a Genes with major mutations (frameshift mutations).
