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.

Similarly to the siblings which inherit some traits from mother or father, in the process of evolution, two organisms can have some similar traits because they inherited them from a common ancestor. Similarities seen among related organisms suggest that they have a common ancestor.

Answer:

According to the characteristics given and what the image shows, the species to which the frog corresponds is Bufo boreas.

Explanation:

Options for this question are:

Bufo marinus .
Litoria caerulea .
Bufo boreas. 
Acris crepitans.

Bufo boreas is a species belonging to the family Bufonidae, very common in North America, constituting an anuro amphibian.

The appearance of B. boreas is that of a thickened and irregular skin, due to multiple warts found on its surface. Additionally it has a stripe or line in its dorsal region, which extends from the head to the tail.

These characteristics, together with the description given, make it possible to establish that B. boreas is the species that can be observed in the picture (see image).
