Increase in the number of histone genes in case of their deficiency in Drosophila melanogaster.
We have determined the number of histone structural genes in D. melanogaster heterozygotes for two different deficiencies of a histone locus in the 2d chromosome. The results indicate a possibility of histone genes increasing in number in the case of their deficiency through magnification and compensation, as has been shown for rRNA genes by other authors.
