Answer:

An index fossil is also known as guide fossils or indicator fossil. They are fossils used to determine and identify geologic periods.

The main characteristics of an index fossil include :

1.It must be distinctive.

2.It must be widespread.

3. It must be abundant

4. It must be limited in geologic time.

Due to trends and studies of most fossil-bearing rocks being formed in the ocean, the major index fossils are mostly marine animal or plant organisms.

Vesnalui [34]

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.

pooled image-base screening of mitochondria with microraft isolation distinguishes pathogenic mitofusin 2 mutations | communicat
Genrish500 [490]

Screening of mitochondria which is pooled image-based with micrograft isolation distinguishes pathogenic mitofusion to mutations.

<h3>What is pooled screening?</h3>
  • More complicated strategies were needed for pooled screening platforms that include complex traits only visible under a microscope. There are a few methods for maintaining information about the cell's physical location, which is necessary for mapping phenotypic to disruption.
  • Using customized non-commercial sequencing rigs, some platforms use in situ sequencing (ISS) to produce sequencing findings that include positional data of a particular cell. Other technologies use targeted cells to photoactivate endogenous fluorophores, which are then subjected to FACS-seq.
<h3>What is Mitochondria?</h3>

Mitochondria is termed as the power house of the cell as it provides the energy and power to the overall cell.
