Question

Sometime within the last 10,000 years, a population of the white trout lily gave rise to a new species. The geographic range of the new species is entirely within the geographic range of the original species. Which of the following is described by this example?a. extensive gene flow.

b. anagenesis.
c. sympatric speciation.
d. allopatric specation.

Answer 1

Option C

Step-by-step explanation:

In case of sympatric speciation, the new species arises from an existing species and these two generation species continue to stay in the same geographical habitat as is the case in this question.

An example of sympatric speciation is hawthorn fly which exhibit sympatric speciation on the basis of suitable egg laying area. The two generations of hawthorn stay in the same area but they do not mate or interact with each other.

Hence, option C is correct

Answer 2

Sympatric speciation.

Step-by-step explanation:

Speciation may be defined as the process of formation of new species. Three main types of speciation are allopatric speciation, sympatric speciation and parapetric speciation.

The new species might generate due to the mutation, gene flow, natural selection ad gene flow. The sympatric speciation is the new formation of the species occur in the same geographical area. The new species and the old species shares the same geographical area.

Thus, the correct answer is option (c).
