The passing of traits from parents to offspring

The study of how traits are passed from parents to offspring

offspring of two plants or

animals with different forms of the

same trait

A genetic factor that is blocked by the presence of a dominant factor

The different forms of a gene

occurs when both

alleles can be observed in the

offspring's phenotype

A section on a chromosome that has genetic information for one trait

The two alleles that control the phenotype of a trait (EE, Ee, ee)

If the two alleles of a gene are different

When the two alleles of a gene are the same

occurs when

the offspring's phenotype is a

blend of the parents' phenotypes

How a trait appears

An inheritance pattern in which multiple genes determine the phenotype of a trait

A model used to predict possible genotypes and phenotypes of offspring

An organism's genetic material

A change in the nucleotide sequence of a gene

A molecule made of a nitrogen base, a sugar, and a phosphate group

The process of copying a DNA molecule to make another DNA molecule

A type of nucleic acid that carries the code for making proteins from the nucleus to the cytoplasm
