Answer:
Mitochondrial DNA.
Explanation:
Mitochondria is known as the power house of the cell and one of the important organelle responsible for the production of energy. Mitochondria contains its own DNA.
To understand the maternal ancestor history, the mitochondria DNA must be studied. The mitochondria is solely obtained from the mother as the egg contains large amount of cytoplasm that contains mitochondria. The mitochondria can never be inherited from paternal origin as the sperm contains few amount of cytoplasm and mitochondria.
Thus, the answer is mitochondrial DNA.
The granulocytes have been commonly recognised and distinguished histologically by their nuclear shapes and sizes. They contain multi-lobed nuclei, each lobe connected by a short region of nucleoplasm.

Answer:
Options I and II
Explanation:
Evolution refers to the changes that occurs in the morphology, appearance and behavior of an organism over a due course of time. This changes occurs due to the natural selection method, where organisms undergoes changes and adapts to the newly habitable environment.
The above given options I and II are the evidences of evolution. The similarities in terms of bones and their defined structure between the bat wings and porpoise fins are signs of evolution that has taken place over a definite span of time. Also, the changes in the various breeds of dog that are caused by the artificial selection method is also an example of evolution.
Thus, the correct answers are options I and II.
Let me explain something that can make you easily understand ok?
So as you know, humans has 46 chromosomes right?
Also, you know that when a gamete is formed there are 2 cell infused to form that 46 chromosomes. (The human cell and sperm)
IF the cells has 46 chromosomes each and it infused with another 46 chromosomes then the total will be 92 chromosomes and not 46 chromosomes. That's why the cell produced only has 23 chromosomes which is fewer so that when it form a genetic material, the total chromosomes will be 46 chromosomes.
Sorry if my english sucks, hope you understand REEEEE
you Are welcome
