Front

What are mutations?

Back

Mutations are changes in the DNA sequence of an organism's genome.

Front

What is the primary reason for changes in a mouse population over time?

Back

The primary reason is natural selection, where certain traits (like color) affect survival and reproduction.

Front

Which organisms are most likely to survive in a changing environment?

Back

The best adapted organisms are most likely to survive.

Front

What is Hardy-Weinberg equilibrium?

Back

A condition in a population where allele frequencies remain constant over generations, requiring no natural selection, mutation, migration, or genetic drift.

Front

What is stabilizing selection?

Back

Stabilizing selection is a type of natural selection that favors average traits and reduces extremes, leading to a decrease in variation.

Front

What is directional selection?

Back

Directional selection is a type of natural selection that favors one extreme phenotype over others, causing a shift in allele frequency.

Front

What is disruptive selection?

Back

Disruptive selection is a type of natural selection that favors extreme phenotypes at both ends of the spectrum, leading to increased variation.

Front

What is the significance of allele frequency in a population?

Back

Allele frequency indicates how common an allele is in a population, which can affect genetic diversity and evolution.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can introduce new alleles and increase genetic diversity.

Front

What is natural selection?

Back

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