Question:

Beetle pollinators of a particular plant are attracted to its flowers' bright orange color. the beetles not only pollinate the flowers, but they mate while inside of the flowers. a mutant version of the plant with red flowers becomes more common with the passage of time. a particular variant of the beetle prefers the red flowers to the orange flowers. over time, these two beetle variants diverge from each other to such an extent that interbreeding is no longer possible. what kind of speciation has occurred in this example, and what has driven it?

Answers

Sympatric speciation, habitat differentiation

B. Sympatric speciation, habitat differentiation.

Explanation:

The right answer to our question is B, Sympatric speciation, habitat differentiation.

Edward Bagnall Poulton derived the term sympatric speciation in 1904. It is a mode of speciation, which entails new species emerging from an ancestral species that is still alive and extant. Both the emerging and ancestral species will exist in the same zone.

This speciation is found more in plants. There are different types of these speciations. Habitat differentiation is seen within sympatric speciation. It is found when mutations that exist in the same zone can make use of varying conditions. Allopatric speciation and parapatric speciation are the other types of speciation.

B. Sympatric speciation, habitat differentiation

Explanation:

In the given example, no geographical barrier has been operational to isolate the two populations of the beetles so as to prevent interbreeding between them. On the other hand, the two variants are present together while developing isolating reproductively from each other. Therefore, it represents sympatric speciation.

The two variants mate inside the flowers of different colors. Since their mating sites are different colored flowers, they are not able to interbreed. This represents habitat differentiation as the one variants of beetle reproduce inside orange the colored flowers while the other inside the red-colored flowers. They develop a tendency to reproduce inside the different habitats (a habitat is a region where an organism lives and reproduces).

B

Explanation:

Allopatric speciation means the process happened because of a physical barrier while sympatric speciation means they diverged while being in the same region.

In this beetle example, divergence happens in the same geographical area. It is a sympatric speciation.

The mutant version of the plant becomes more common with the passage of time and one variant of beetle prefers it. Knowing that beetles not only pollinate the flowers but also mate inside them we can deduce there is an environmental barrier that over time makes them diverge. Individuals exploit different conditions from the same region.

Correct answer is B, sympatric speciation and the drive force is habitat differentiation.
