a drug called an antibiotic​

Explanation:

A drug called antibiotics is a treatment used for a bacterial infection such as strep throat.

Antibiotics are medicines that are used to treat a wide range of bacterial infections.

These drugs destroys bacteria by preventing them from replicating and reproducing their copies. This way the strain is unable to continue one of its essential life function.

These substances are active against bacteria and provides a toxic condition for them to replicate.

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.

What is a recombination? How is it different from mutation
8_murik_8 [283]
Recombination
: the process occurring in Meiosis I, in which offspring are able to obtain unique traits resulting in an array of different phenotypes (physical appearances).

Prophase I,
the homologous chromosomes line up in the middle of the cell and exchange segments of alleles, and then lining up in the cell in a NON-uniform way.... therefore resulting in genetically unique offsprings rather than identitical.


Mutations are result of evolutionary factors. They create genetic diversity that helps species adjust to different climates, behaviours and foods. Mutations that occur in a fit indivual can result in offspring that are genetically more successful in adjustments to different climates, foods, and environments.


All in all Recombination results in unique looking indivuals, whereas mutations result in greater survival chances of a species.
