The current theory is that chloroplasts are descendants of symbiotic cyanobacteria that lived within eukaryotic cells. If we look at their respective genomes, however, we see that the cyanobacteria have many more genes than do chloroplasts. Where did these genes goes.

The correct answer is - the most of gene are lost during the process of evolution and rest of the genes are incorporated or transported to the nucleus.

Explanation:

The theory of the endosymbiotic is states that the origin of eukaryotes that chloroplast and mitochondria are originated when the eukaryotes like amoeba engulfed by prokaryotic cells.

Such cells and chloroplast they have less genes and DNA in them as compared to cyanobacteria as they were not benefit in the host cell and either transfer to nucleus.

Thus, the correct answer is - the most of gene are lost during the process of evolution and rest of the genes are incorporated or transported to the nucleus.
