Evolutionary conservation of homeotic gene organization and transcriptional expression in fruit flies and mice is seen in the similarity between the Hom-C cluster on Drosophila chromosome 3 and the four Hox gene clusters in the mouse genome.

 

According to this figure, Which of the following statement is correct?

#Unit 5. Developmental Biology
  1. Genes with similar structures occupy the same relative positions on each of the four chromosomes, and paralogous gene groups display similar expression patterns.
  2. Genes with similar structures occupy the different positions on each of the four chromosomes, and paralogous gene groups display similar expression patterns.
  3. Genes with similar structures occupy the same relative positions on each of the four chromosomes, and orthologous gene groups display similar expression patterns.

  4. Genes with similar structures occupy the same relative positions on each of the four chromosomes, and orthologous gene groups display different expression patterns.
