Results
Specimen 1C: embryonic day 12.5 (more )
Structure Level Pattern Image Note
TS20: foot Ambiguous 1C

Specimen 1F: embryonic day 12.5; Alx4lst/Alx4lst (more )
Note: The embryos were selected by their phenotype (preaxial polydactyly). It is possible that the genotype could be a heterozygous mutant.
Structure Level Pattern Image Note
TS20: foot Present Regionally restricted 1F Ectopic expression in the anterior portion of the apical ectodermal ridge.

Specimen 1I: embryonic day 12.5; Lx/Lx (more )
Note: The embryos were selected by their phenotype (preaxial polydactyly). It is possible that the genotype could be a heterozygous mutant.
Structure Level Pattern Image Note
TS20: foot Present Regionally restricted 1I Ectopic expression in the anterior portion of the apical ectodermal ridge.

Specimen 1L: embryonic day 12.5; Xpl/Xpl+ (more )
Note: The embryos were selected by their phenotype (preaxial polydactyly). It is possible that the genotype could be either a hemizygous male mutant or a homozygous female mutant.
Structure Level Pattern Image Note
TS20: foot Present Regionally restricted 1L Ectopic expression in the anterior portion of the apical ectodermal ridge.
