Evolution/Natural Selection

Front

What is the process of choosing parent organisms for desired characteristics called?

Back

Artificial selection

Front

What is an example of the founder effect?

Back

A small group of iguanas floats to an island, starting a new population.

Front

What characteristic do all organisms on a specific cladogram share?

Back

Partial binocular vision & opposable thumbs

Front

What type of speciation occurs when new species evolve from a single ancestral species while inhabiting the same geographic region?

Back

Sympatric speciation

Front

What is the common ancestor number of organisms C and D in a cladogram?

Back

4

Front

Define natural selection.

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between allopatric and sympatric speciation?

Back

Allopatric speciation occurs when populations are geographically isolated, while sympatric speciation occurs within the same geographic area.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is the significance of the Hardy-Weinberg principle?

Back

The Hardy-Weinberg principle provides a mathematical model to study genetic variation in a population under ideal conditions.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on shared characteristics.
