Spermatids of Laccifer lacca are binucleate to start with, but become quadrinucleate due to the fusion of sister cells.
Of the four nuclei two are euchromatic and the other two are heterochromatic in nature. In the course of development each euchromatic nuclei develops a nuclear outgrowth by the elongation while the heterochromatic pair disintegrates taking no part in sperm formation. This results in the suppression of sperm formation in half of the gametic nuclei.
The elongated euchromatic nucleus eventually transforms itself into the core of the sperm without rejecting any nuclear part. Thus each cyst carries within it 32 sperms in the form of a bundle which at a subsequent stage of development splits into two subunits carrying 16 sperms each. The sperms are thin and thread-like ard are compactly arranged inside the bundle.
