The tg238a/+ pair used to produce the embryos for this experiment(tg238a-C) have a high degree of left-right patterning defects (28%). The fa20r/+ pair used to produce the embryos for this experiment(fa20r-M21) have a low degree of left-right patterning defects (2%). See Table S1 for details. Numbers in parentheses indicate embryos with correct heart looping in each category
