#Question id: 7283


The Drosophila orthodenticle gene and the vertebrate Otx genes are homologous and provide a good example of the conservation of gene function during evolution. Which of the following statement is correct regarding to the expression of gene expression.

#Unit 5. Developmental Biology
  1. Orthodenticle is expressed in the posterior region of the future Drosophila brain. In mice, Otx1 and Otx2 are expressed in overlapping domains in the developing forebrain and midbrain.
  2. Orthodenticle is expressed in the anterior region of the future Drosophila brain. In mice, Otx is expressed in overlapping domains in the developing forebrain.
  3. Orthodenticle is expressed in the posterior region of the future Drosophila brain. In mice, Otx1 and Otx2 are expressed in the developing limb.
  4. Orthodenticle is expressed in the proximal region of the future Drosophila limb. In mice, Otx1 and Otx2 are expressed in the developing limb.
