WebLearn about genetic inheritance and revise the different types of genes for GCSE Biology, AQA. WebGenetic crosses are made by mixing conidia from genetically marked strains and selecting for a heterokaryon. Cleistothecia produced by the heterokaryon are microdissected, cleaned of adhering peripheral cells, crushed, and the ascospores are grown out. In any given cross, some cleistothecia will result from each parent's self-fertilization.
