Which of the following did Hermann Muller determine when studying eye color variegation in Drosophila melanogaster? A) Transcription of the w⁺ allele was directly influenced by the level DNA compaction. B) The w⁺ allele was expressed in the cell if the heterochromatin spread covered its new location. C) The chromosome region immediately surrounding the centromere was typically a euchromatic and contains a large number of expressed genes. D) The pattern of variegation was the same from fly to fly and that the two eyes of a single fly also had the same variegation patterns. E) The w⁺ allele had been deleted in cells that produced the white eye patches.
