What is inheritance in genetics?

Back

Inheritance is the process by which genetic information is passed from parents to their offspring, determining traits such as eye color.

Front

What is an acquired trait?

Back

An acquired trait is a characteristic that is not inherited genetically but is developed through environmental influences or experiences.

Front

What can cause bacteria to become resistant to antibiotics?

Back

Bacteria can become resistant to antibiotics if they are not taken correctly, such as not completing the prescribed course.

Front

How do embryos of different organisms compare?

Back

Embryos of different organisms often look surprisingly similar, indicating common ancestry.

Front

What do fossils tell us about organisms?

Back

Fossils provide evidence of how much organisms have changed over time and can show the evolutionary history of species.

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.

Front

What is a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved.

Front

What is the significance of homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, which may be beneficial, harmful, or neutral, and contribute to evolution.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is the intentional breeding of organisms for desired traits, while natural selection occurs without human intervention.
