Horizontal transfer of chloroplasts across the eukaryotic tree genetic merger rarely happens, but it does happen and it can happen. Parasites with 2o chloroplast can be targeted for drugs: plasmodium. Malaria was a free-living red alga at one point then went through genetic merger chloroplast has lost photosynthetic function then why does it hold on to it? it is still essential for metabolism. How many distinct genomes can a eukaryote have? genome: a set of genetic instructions within a biological compartment could have 3. Nuclear genome, mtco, and chloroplast (plants, malaria) could have 2. Nuclear genome, mtco + or lost chloroplast genome (rafflesia, Mutation happens so mtco loses the genome this independently occurs multiple times.

One tiny nuclear genome; and it has lost mtco gene, thus, an empty mtco.
