You find that a gene called Scute is expressed in the forelimb bud. Mis-expression of Scute in the flank of a chicken embryo results in an extra (ectopic) forelimb bud. In a separate study, you find that conditional deletion of Scute in the forelimb bud does not affect limb development. What do these findings demonstrate?

Accepted Answer

Scute  is sufficient, but not required to form a forelimb bud

Answer

Scute  is both necessary and sufficient to form a forelimb bud

Answer

Scute  is required, but not sufficient for forelimb development

Answer

Scute  is only important in chicken limb development
