Sympatric speciation is _____.

Hint: It is due to a radical change in the genome.

a. especially important in the evolution of island species
b. the appearance of a new species in the same area as the parent population
c. the emergence of many species from a single ancestor
d. initiated by the appearance of a geographic barrier
e. the process by which most animal species have evolved

Explanation: sympatric speciation is the apprearance of new individual from the ancestor and they both live together in the same environment. It is the genetic variation that occurs within individual after interrracting with each other over a long time.

Individual species after staying with each other for a long time tends to bring about new type and offspring and this offspring also lives among the ancestor even when they are not related. Example is a maggot living in apples after a long time the offspring also take the apple as there host cell.

There are three geographic mode of speciation, Allopatric speciation,sympatric speciation and parapatric speciation.

Allopatric--- Appearance of new species from geographic Isolation of some species.

Parapatric---appearance of new species from the meeting of two diverge population
