Answer 1

Sympatric speciation generally requires disruptive selection, which favors extreme phenotypes, leading to reproductive isolation and creation of new species within the same habitat.

Step-by-step explanation:

In general, sympatric speciation requires the action of disruptive selection acting against hybrids. Disruptive selection plays a crucial role in sympatric speciation by favoring extreme phenotypes over intermediate ones, thereby driving the divergence within a population sharing the same habitat. This pattern of selection can eventually lead to reproductive isolation and form new species without physical barriers. It contrasts with directional selection which favors one extreme phenotype and stabilizing selection that favors the intermediate phenotype, or artificial selection that is influenced by human choice.

Answer 2

disruptive

Step-by-step explanation:

Sympatric speciation is a speciation (evolution of new species) that occurs when one group of population becomes isolated, but stays in the same geographic location as the rest of the population. Through time, these two group evolve independently and become different species.

The model that shows this type of speciation involves disruptive selection: homozygous individuals are favoured over heterozygous in a population, which leads to speciation.
