Embryos’ Ancestors

Several generations ago, the predecessors of mutants 1-4 were treated with EMS*. The predecessors all looked like the WT in every aspect – such as appearance, reproductive ability, life span, etc. The environment was also identical for all predecessors.

Embryos’ Parent Info
Movie Subject	Growth Temperature Changes in Larva Stage **	Phenotype	Genotype
WT	Yes	WT	WT
Mutant 1	Yes	Same as WT	zyg-1(oj7)
Mutant 2	Yes	Same as WT	zyg-1(b1)
Mutant 3	Yes	Same as WT	zyg-1(it4)
Mutant 4	Yes	Same as WT	zyg-1(it37)

* EMS (ethylmethanesulfonate) is a mutagen.

** As you can see on the “Glossary” page, zyg-1 is a temperature sensitive mutant. Thus, in order to have the mutation expressed in the mutant worms, the growth temperature needs to be changed in the worms’ larval stage. Therefore, the worms offspring will show the mutation phenotypes.
