Question

Explain: One of the tallest dog breeds is the Great Dane, which stands over a meter tall. One of the shortest is the Pomeranian, which stands about 20 centimeters tall. Based on what you have learned about artificial selection, how were these two breeds developed?

Answer 1

Breeding the largest or smallest dogs together.

Answer 2

To breed larger or smaller dogs, artificial selection allows the crossing of dogs of varying sizes, so that through the genetic combination of these dogs the offspring has a larger size or a smaller size.

Step-by-step explanation:

Artificial selection is the process made by the human being, where living beings are crossed in a provoked way seeking to generate descendants with a specific, favorable and desirable characteristic for the human being. An example of this is the use of natural selection to raise dogs smaller or larger than normal.

To breed larger or smaller dogs, artificial selection allows the crossing of dogs of varying sizes, so that through the genetic combination of these dogs the offspring has a larger size or a smaller size. Thus, if it is desirable for the offspring to be smaller in size, dogs of reduced size should be crossed, while, if it is desirable to obtain offspring with the larger size, dogs of larger sizes should be crossed.
