Which of the following did Hermann Muller determine when studying eye color variegation in Drosophila melanogaster?
◦ 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.
◦ The w+ allele was expressed in the cell if the heterochromatin spread covered its new location.
◦ Transcription of the w+ allele was directly influenced by the level DNA compaction.
◦ The chromosome region immediately surrounding the centromere was typically a euchromatic and contains a large number of expressed genes.
◦ The w+ allele had been deleted in cells that produced the white eye patches.
