10 Questions
What is the main factor that leads to speciation?
Geographical isolation and separation of populations
How do different selection pressures contribute to speciation?
They favor different phenotypes in each population
Why is gene flow important in preventing speciation?
It allows for breeding between different populations
How can the formation of new species be confirmed?
By analyzing DNA, amino acid sequences, or structural features
What happens if individuals cannot produce viable and fertile offspring?
They are considered different species
What is the ultimate result of speciation?
No gene flow between populations
How do geographical barriers like mountain ranges or rivers contribute to speciation?
They prevent gene flow between separated populations
What is the significance of genetic divergence in the process of speciation?
It leads to populations becoming unable to interbreed
How can DNA, amino acid sequences, or structural features be used to confirm speciation?
By revealing significant differences between populations
What defines two populations as separate species?
Inability to produce viable and fertile offspring
Learn about the process of speciation, which occurs when a population is separated and isolated from another group, leading to the formation of new species due to lack of gene flow and different selection pressures. Discover how genetic variation accumulates over time, preventing interbreeding.
