What is needed for sympatric speciation?
Just strong disruptive selection on a trait
Just assortative mating based on a trait
Both disruptive selection and assortative mating based (acting on two different traits)
Both disruptive selection and assortative mating based (acting on the same trait)
A combination of disruptive selection and assortative mating (both based on the same trait) and geographic isolation
a.)Just strong disruptive selection on a trait
b.)Just assortative mating based on a trait
c.)Both disruptive selection and assortative mating based (acting on two different traits)
d.)Both disruptive selection and assortative mating based (acting on the same trait)
e.)A combination of disruptive selection and assortative mating (both based on the same trait) and geographic isolation
Explanation / Answer
Speciation can limit gene flow ,arriving at Sympatric speciation when individuals are found in the same geographic locale is a challenge. Some kind of assortative mating is also required.
Specifically ,assortive mating is the way in which gene flow is eliminated in sympatric soeciation.
Answer is "b".assortive mating.
