Figure 7.

Comparison of HOXA13 expression patterns in the mouse, chicken and tammar. Patterns of mRNA expression in the mouse and chicken were traced from previously published data (Mouse: [43,54,55]; chicken:[42]). Strong staining is indicated in dark blue and weaker expression is represented in light blue. Dotted lines indicate digital rays.
