The basic physical and functional unit of heredity made up of DNA

A form of artificial selection where humans deliberately breed plants and animals for desired traits

A characteristic that is passed from parent to offspring

A diagram that shows how traits are passed through multiple generations

The measure of the likelihood that a particular event will occur, often expressed as a fraction or percentage.

An organism that has two different alleles for a particular gene

The direct manipulation of genetic material to alter the hereditary traits of a cell, organism, or population

The study of heredity and the variation of inherited characteristics.

A trait that masks the effect of a recessive trait when both are present; it is expressed in the phenotype.

A tool used to analyze the possible allele combinations of the offspring between two individuals

Process by which organisms with favorable traits produce more successful offspring than organisms with less-favorable traits, causing the favorable traits to become more common in the population

A trait that is beneficial to an organism and will likely be chosen by natural selection
