Heredity and Genetics Vocabulary

What is a Gene?

• The set of information that controls a trait; code in the DNA.

• The scientific study of heredity.

• An allele that is masked when a dominant allele is present.

What are offspring?

• Having two different alleles for a trait (one dominant, one recessive)

• A number that describes how likely it is that an event will occur.

• children or young of a particular parent. A descendant.

What is a trait?

• An organism that is genetically identical to the parent organism.

• A characteristic that an organism can pass to offspring through genes.

• Having two identical alleles for a trait (both dominant or both recessive)

A trait that is expressed as a combination of your genes and the environment. (ie. Skin color) - is called what?

What is a Punnett Square?

• a square diagram that is used to predict an outcome of a particular cross or breeding experiment

• An allele that is masked when a dominant allele is present.

• The scientific study of heredity.

What is an Allele?

• The passing of traits from parents to offspring.

• a sudden difference or variation from the parent type in one or more inherited characteristics, caused by a change in a gene or a chromosome

• The different forms of a gene.

What is Genetics?

• The different forms of a gene.

• The scientific study of heredity.

• The set of information that controls a trait; code in the DNA.

What is probability?

• The passing of traits from parents to offspring.

• An organism's genetic makeup or allele combinations.

• A number that describes how likely it is that an event will occur.
