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 compen
The deficiency of the 38B-40 region containing histone genes in one of the 2nd chromosomes of D. melanogaster triploid intersexes increases the template activity of X-chromosomes both in vivo and in vitro without noticeably affecting autosome activity. This deficiency in the heterozygous state inhib
