The study of how traits are passed from parents to off spring

A genetic factor that blocks another genetic factor

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

Different form of a gene

Molecule made of a nitrogen base, a sugar, and a phosphate group that forms a basic structural unit of DNA

Having the same two alleles of a gene

Occurs when multiple genes determine the phenotype of a trait

Ribonucleic acid that carries the code for making proteins

How a trait appears is expressed

Organisms genetic material

Change in the nucleotide sequence of a gene

Section on a chromosome that has a genetic information for one trait

Having two different alleles of a gene

Occurs when both alleles can be observed on the offsprings Phenotype

To reach logically necessary end by reasoning

Model used to predict possible genotypes and phenotypes of offspring

Process of copying a DNA molecule to make another DNA molecule

Occurs when the offsprings phenotype is a blend of the parents phenotype

Offspring of two plants or animals with different forms of the same trait
