1.   But its live counterpart does not glow, even though tests show the jellyfish genes are present.

2.   But there might be some mistakes doing it this way, he says, because human genes are longer.

3.   If the gay gene is in the mitochondria, then a conspiracy theory springs to the devious minds of Hurst and Haig.

4.   If we leap far enough, all the genes will be copies of one single gene in our ancestral population.

5.   Once isolated, the mutant gene will be the second gene known to increase the risk for the brain disorder.

6.   Over short time spans then genes are not the separate units of selection Dawkins supposes.

7.   The glow showed that the gene was active.

8.   Therefore, a gene is by definition the descendant of a gene that was good at getting into future generations.

9.   These genes are involved in determining the basic structure of cells.
