0 -9.8 m/s

Is this a question of an answer

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.

What are your choices. i believe it might be mitochondria but i will know for sure when i see the choices. let me know okay i'm happy to answer
