About this work

Description

Bloxam thought that the main objection from the Danish Patent Office was that the "uniting of the two nuclei in your [Pontecorvo's] process can properly be regarded as a sexual process". In the copy of Pontecorvo's response letter he disputes this by explaining how "it was possible to discover that in A. nidulans, in addition to the sexual cycle and side-by-side with it, there was an essentially different process of genetic recombination which we named "parasexual", and which is now universally known under such name".

This letter provides a good overview, in Pontecorvo's own words, of his research on Aspergillus and the parasexual cycle.
