9. The Pitx1 protein has important functions in various tissues during stickleback development. The complete absence of the Pitx1 protein from all tissues is lethal to the organism. However, as shown in the film, Pitx1 protein can be absent in the pelvis alone, and the fish survives. The absence of Pitx1 in the pelvis confers a unique phenotype. Mark the fish below that lacks Pitx1 expression in the pelvis. a b
