Description: | MOUSE TESTIS BOUIN FEULGEN & LIGHT GREEN 20-2-43 (printed on a paper label gummed to the slide). There have been alterations made to the label; BOIUN has been scored out and 6 days std added. The 20-2-43 has been changed to 20-6-43 and Fix.: Acetic Alcohol and chromic added in black pen. MANU PONTERCORVO,Guido. June 20, 1943 Glasgow University, Glasgow, Scotland. This is a specimen of the testes of a mouse. Probably a laboratory mouse, which is an inbred variety of *Mus musculus domesticus*, the domestic mouse. The fixative is unknown but at about this time a mixture of acetic acid, alcohol and chromic acid was used.
The specimens are stained with Feulgen's stain, a specific histochemical test for chromosonal material or DNA was published by Robert Feulgen (1884-1955) German nucleic acid biochemist and cytochemist, and H. Rossenbeck, in 1924.
The process undergone was meiosis; the cell division in sexually reproducing organisms causing a reduction in the number of chromosomes, in the reproductive cells, from diploid (paired chromosomes) to haploid (single chromosomes) thus leading to the production of gametes (asexual) animals or plants.
