- Question #4: Assume you are able to use CRISPR to create an allele that will convert a cross-pollinated, sexually reproducing crop plant into an obligate apomict. Your edited obligate apomict plants retains all the CRISPR "machinery" necessary to convert the "sexually reproducing" allele to the "obligate apomict" allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?
