A group of scientists placed four groups of icefish embryos (group of cells that will become a baby) into water tanks at various incubation (heat) temperatures. After 24 hours, they counted to see how many embryos developed normally and how many had some type of damage. Their results are shown below.
What can scientists conclude about the effect of temperature on developing icefish embryos?
What similarities and differences do you observe between the Normal Icefish and the Incubated Icefish?

What is CRISPR/Cas9?
How do scientists "edit" (remove/add genes to) sequences of DNA?
How does CRISPR/Cas9 relate to gene expression?
When CRISPR/Cas9 is used to continually express the CLA1 gene, then of the CLA1 protein is produced, resulting in .
When CRISPR/Cas9 is used to deactivate the ODI2 gene, then of the ODI2 protein is produced, resulting in .
When CRISPR/Cas9 is used to activate the MENTA gene, then of the MENTA protein is produced, resulting in .
When CRISPR/Cas9 is used to turn off the AUD6 gene, then of the AUD6 protein is produced, resulting in .
When CRISPR/Cas9 is used to inactivate the VAT2 gene, then of the VAT2 protein is produced, resulting in .
Which gene or genes do you think might be responsible for creating the mutations in the incubated icefish? Why do you think so?
A mutation occurs only in the individual, so it get passed on to offspring.
A mutation occurs in the sex cells (sperm and egg), so it get passed on to offspring.
Based on the offspring of the CLA1 parents, the CLA1 gene had a mutation because .
The offspring of ODI2 the mutation, so this gene had a mutation.
Based on the evidence, the genetic mutation in MENTA , so this gene had a mutation.
If none of the offspring of AUD6 have the fused fin, what type of mutation was this?
What type of mutation is VAT2?
