Genetics

DNA

• deoxyribonucleic acid, contains all of the genetic information of an organism

• deoxyribonucleic acid, a type of protein

• deoxyribonucleic acid, responsible for energy production

• deoxyribonucleic acid, a carbohydrate molecule

Co-dominant

• the state in which two genetic traits are fully expressed and neither dominates

• a genetic condition where one trait completely masks another

• a situation where only one trait is expressed

• the absence of any genetic traits

Law of Segregation

• Mendelian law stating that two alleles for each trait separate during meiosis

• A principle that states that traits are inherited independently of one another

• A theory that explains the blending of traits from both parents

• A concept that describes the dominance of one allele over another

Phenotype

• An organism's genetic makeup.

• An organism's physical appearance, or visible traits.

• The process of natural selection.

• The study of heredity.

Chromosomes

• A chromosome is a package of DNA with part or all of the genetic material of an organism.

• Chromosomes are structures that only exist in prokaryotic cells.

• Chromosomes are made up of proteins and lipids.

• Chromosomes are responsible for the production of energy in cells.

Dominant

• Describes a trait that covers over, or dominates, another form of that trait.

• A trait that is always expressed regardless of the other allele.

• A trait that is hidden when a dominant allele is present.

• A trait that is only expressed in the absence of a dominant allele.

Law of Independent Assortment

• the law that states that genes separate independently of one another in meiosis

• the principle that traits are inherited together

• the concept that all genes are linked on the same chromosome

• the rule that dominant traits always mask recessive traits

Pedigree

• A type of genetic mutation

• A chart or 'family tree' that tracks which members of a family have a particular trait

• A method for cloning organisms

• A technique for measuring blood pressure

Recessive

• trait of an organism that can be masked by the dominant form of a trait

• a trait that is always expressed in the phenotype

• a trait that is inherited independently of other traits

• a trait that is dominant over all others

Heterozygous

• An organism that has two identical alleles for a trait

• An organism that has two different alleles for a trait

• An organism that has no alleles for a trait

• An organism that has one dominant and one recessive allele for a trait
