Speciation
Biology ⇒ Evolution and Diversity
Speciation starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Speciation.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A population of insects is separated by a newly formed river. Over time, the two groups develop different mating behaviors and can no longer interbreed. What type of speciation has occurred?
Describe how genetic drift can contribute to speciation, especially in small populations.
Describe how polyploidy can lead to speciation in plants.
Describe the difference between prezygotic and postzygotic barriers, giving one example of each.
Describe the role of natural selection in the process of speciation.
Explain the concept of reproductive isolation and its importance in speciation.
Explain the difference between allopatric and sympatric speciation.
Explain why gene flow between populations can prevent speciation.
Explain why polyploidy is more common as a mechanism of speciation in plants than in animals.
