WebDisruptive Selection: The natural selection that favors individuals with severe or unique features over those with typical or intermediate traits is known as disruptive selection.

It is believed that disruptive selection is one of the main forces that drive sympatric speciation in natural populations. The pathways that lead from disruptive selection to sympatric speciation seldom are prone to deviation; such speciation is a domino effect that depends on the consistency of each distinct variable. These pathways are the result of disruptive selection in intraspecific competition; it may cause reproductive isolation, and finally culminate in sympatric speciation. chesterfield indiana post office hoursWebJul 25, 2016 · Jodi supports Lenati's loyalty consulting business serving clients in consumer industries, including: retail, consumer technology, travel & hospitality, … chesterfield indiana food pantryWebStudy with Quizlet and memorize flashcards containing terms like What is an example of genetic drift?
