The mouse research is a way to fish for genes that seem to have a certain effect.

This is actually only true for genes that are not linked to each other.

It's too hot for Gene to stand around out here.

Frog is forced to start the show using a double for Gene.

I wanted to go the opposite way, look for genes that helped people live healthier and longer lives.

For genes of smaller effect, very large sample sizes are likely to be needed.

And that is the only hope for Serrais-some new genes!

"It was a pretty big hit for Gene," she recalled.

This work evolved into searches for specific genes involved in reading and language.

That means there is either no or little change in gene-expression levels for most genes.
