Answer:
A. an increase in genetic diversity
Explanation:
Genetic diversity is the degree of gene variety within a single species (animal or plant). It corresponds to the total number of genetic characteristics in the genetic composition of species or subspecies. Genetic diversity is one of the main aspects of our planet's biodiversity, such as populations and ecosystems.
In the case of Siamese cats, genetic diversity has caused some lineages to change their appearance from classic to modern. This occurred by crossing Siamese cats with cats of other breeds, creating a wide genetic variety that resulted in the change in appearance of these cats.
Answer:
(A) speciation.
Explanation:
Shrinking of water bodies and development of deserts since the Pleistocene ice age produced new vacant niches that could be inhabited by organisms such as fishes. Production of new isolated streams, ponds, and springs allowed the fishes to occupy these new water bodies. Accumulation of genetic variations to become adapted to their new habitat resulted in the evolution of several new species of fishes with many different genetic traits. This represents speciation due to geographical isolation.
