(A) The jaw and a pronounced pelvic spine develop, both developing tissues normally, because the Pitx1 gene is expressed in
(B) Neither the jaw nor a pronounced pelvic spine develop expression in either developing tissue normally because there is no Pitx1 gene
(C) The jaw develops normally, but a pronounced pelvic spine does not develop because the Pitx1 gene is expressed in the developing jaw but not in the developing pelvis
(D) The jaw does not develop normally, but a pronounced pelvic spine does develop because the Pitx1 gene is expressed in the developing pelvis but not in the developing jaw.
