Fig. 2 (A) Method of measuring heart tube angle at 24 h.p.f., illustrated in three flh homozygotes. The examples shown have heart angles of -20°, 0°, and +40°. a, atrium; e, eye; v, ventricle. Arrowheads denote the left and right first aortic arch. Bar 200 μm. (B) Heart tube angle (in degrees) as a function of h.p.f. in brs homozygotes. The embryonic midline is denoted as 0°. The center (origin) of the polar coordinate plot is the site of the caudal end of the heart tube.
