Phenotype of insertional mutants isolated in the large-scale screen

Name	Allele	Phenotype	Visible onset
		Recessive Insertional mutants
no knack	nokhi5	reduced circulation, edema around heart, bent body, jaw does not form, sb−	day 3
bubble brain	bbrhi10	enlarged brain ventricle; yolk disappears from yolk extension, and later development is impaired; embryo dies by day 4–5	late day 1
nearly normal	nanhi14	appears normal except swim bladder does not inflate; not completely penetrant; embryos that develop a swim bladder grow up small	day 5
hi37		reduced head structures; eyes look wide apart, reduced circulation, edema around heart at day 4; jaw does not form; sb−	day 3
hi43		liver structure is defective, blood does not appear to circulate normally through liver, and it darkens; gut tube abnormal; swim bladder fails to inflate but embryos are still alive at 1 week; sb−	day 4
hi61		generally underdeveloped; sb−	day 5
hi63		small head structures including eye and ear; jaw does not develop; sb−	late day 3
hi96		multiple and unusual edemas including around eyes; heart and finally embryo appears as if atop a huge ball; reduced circulation; sb−	day 4
bleached blond	bblhi112	pigmentation is defective in both the eyes and the melanocytes; eyes appear mottled; sb+/−	day 2
		Dominant insertional mutants
hiD862		all fins are abnormally long	young adult
Hagoramo	HaghiD2	stripes are interrupted in body region; this is second insertional allele in this gene	young adult

sb⁻, lacks swim bladder at day 5; sb^+/−, some embryos develop a swim bladder, but most do not.
