Abstract EN
In typical somatic cells, DNA is tightly organized by histones that are necessary for its proper packaging into the nucleus.
In sexually-reproducing animals, the haploid product of male meiosis must be further condensed to fit within sperm heads, thus requiring an even greater degree of packaging.
This is accomplished in most organisms by replacing histones with protamines, which allows DNA to be compacted into the reduced space.
In mammals, protamines are produced after meiosis is complete and are transcribed by the single allele present in the haploid genome that is to be packaged into the sperm head.
Here, we present our findings that protamine expression occurs from both alleles in diploid cells, rather than haploid cells, in two species of Drosophila.
The differential allelic expression of protamines likely influences the selective pressures that shape their evolution.
