A pair-rule gene
in Drosophila called runt controls nervous
system formation. In the mouse, runt controls blood cell
formation and genital structures. In humans, the analog
of runt, when mutated, causes children to lack collar bones,
and the opening at the top of the skull fails to close. What kind
of experiment could tell you whether these genes are conserved in
function?
