Question

. In a hypothetical situation, a certain species of flea feeds only on pronghorn antelopes. In the western United States, pronghorns and cattle often associate with one another in the same open rangeland Some of these fleas develop a strong preference for cattle blood and mate only with other fleas that prefer cattle blood. The host mammal can be considered as the fleas' habitat. If this situation persists, and new species evolve, this would be an example of sympatric speciation and habitat isolation sympatric speciation and temporal isolation allopatric speciation and habitat isolation allopatric speciation and gametic isolation

Answer 1

sympatric speciation and habitat isolation

Step-by-step explanation:

First lets define the key words in the options

Allopatric speciation—allo stands for other and patric represents homeland—it entails geographic isolation of populations from a parent species and succeeding evolution.

Sympatric speciation—sym stand for same and patric represents homeland—it has to do with speciation seen within a parent species residual in one location.

sympatric speciation and habitat isolation✔✔✔

In this case as seen in the scenario, two species live in the same area but different habitats, one on the cattle as fleas' habitat and the other on the pronghorn antelopes as the fleas' habitat. Some of these fleas develop a strong preference for cattle blood and mate only with other fleas that prefer cattle blood.

sympatric speciation and temporal isolation ❌

This involves two species that breed at separate times of day, seasons, years. This can be observed in the brown vs rainbow trout but not in this scenario.

allopatric speciation and habitat isolation❌

This entails geographical isolation and hence cannot be the situation in this scenerio as they are not geographically isolated.

allopatric speciation and gametic isolation❌

It has to involve gametes of separate species coming together without fusing to produce a zygote. In internal fertilization sperm can't strive and external fertilization gametes seems not to recognize one another but this does not has to do with the case study here.
