What is NOT an example of proof of the existence of the emdosymbiotic theory in modern day mitochondria? a. Mitochondria has its own DNA
b. Mitochondria have their own nucleus
c. Mitochondria has it's own membrane
d. Mitochondria has its own ribosomes ​

The correct answer is - option B. mitochondria have their own nucleus.

Explanation:

Endosymbiotic theory is a evolutionary theory which explains how eukaryotic cells evolved from prokaryotic organisms.

Evidences of endosymbiotic theory are:

1. Mitochondria and chloroplasts are double membrane bound cell organelles. The inner membrane probably evolved from the plasma membrane of engulfed bacterium and outer membrane from the plasma membrane or endoplasmic reticulum of the host cell.

2. Almost similar size of mitochondria and chloroplast and bacteria and their ribosomes.

3. Cristae of mitochondria resemble the folded membranes is groups of bacteria.

4. Mitochondrion and chloroplast both have circular DNA similar to those of bacterial DNA.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
