Genetics and Evolution Quizs

Says that organisms with better adaptations tend to survive longer, reproduce more often, and pass those beneficial traits on to their offspring.

• Natural Selection

• Evolutionary Adaptation

• Genetic Drift

• Artificial Selection

Organisms that are so similar that they can reproduce and produce fertile offspring.

• Genus

• Species

• Family

• Order

A distinguishing quality that can be traced through generations.

• Trait

• Characteristic

• Feature

• Attribute

The fact that all organisms have DNA as their genetic material/instructions is evidence that… all organisms most likely descended from a common ancestor.

• Common Ancestor

• Multiple Origins

• Independent Evolution

• Convergent Evolution

A trait that always shows up in an organism when present, shown with a capital.

• Recessive Trait

• Dominant Trait

• Genetic Trait

• Phenotypic Trait

Changes in DNA that result in new traits/adaptations.

• Genetic Mutations

• Phenotypic Variations

• Chromosomal Aberrations

• Environmental Influences

When all members of a species die out completely.

• Extinction

• Evolution

• Adaptation

• Migration

A change in a gene or chromosome that may result in changes that may be helpful, harmful, or have no effect.

• Genetic Mutations

• Chromosomal Aberrations

• Gene Therapy

• Phenotypic Variations

When an organism has different alleles for the same trait such as Tt.

• Homozygous

• Heterozygous

• Dominant

• Recessive

A change in the sequence of DNA that results in a change in a gene.
