Structure	Level	Pattern	Image	Note
TS14: rhombomere 2	Strong		4B	The mutant embryo has the same expression pattern as the control.
TS14: rhombomere 4	Strong		4B	The mutant embryo has the same expression pattern as the control.
TS14: rhombomere 1	Weak		4B	The mutant embryo has the same expression pattern as the control.
TS14: rhombomere 3	Weak		4B	The mutant embryo has the same expression pattern as the control.
TS14: rhombomere 5	Weak		4B	The mutant embryo has the same expression pattern as the control.

Structure	Level	Pattern	Image	Note
TS14: rhombomere 5	Present		4C	This is believed to be a mis-specification of rhombomere 4 at the level of rhombomere 5.
TS14: rhombomere 3	Absent		4C
TS14: rhombomere 4	Present	Regionally restricted	4C	There is an anterior region that does not express.

Structure	Level	Pattern	Image	Note
TS14: rhombomere 3	Present	Regionally restricted	4D
TS14: rhombomere 5	Present		4D	This expression is interpreted as rhombomere 4 expression at the level of rhombomere 5.
