Gene: the basic unit of heredity that consists for a segment of DNA on a chromosome.

Heredity: Hereditary transmission of the physical and genetic qualities of parents to their offspring; the biological law by which living beings tend to repeat their characteristics in their descendants.

Allele: One of a number of alternative forms of the same gene occupying a given position on a chromosome.

Phenotype: The appearance of an organism based on a multifactorial combination of genetic traits and environmental factors, esp. used in pedigrees.

Genotype: the genetic makeup of an organism.

Dominant: a term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype.

Recessive: a term that describes an allele that is not expressed when combined with a dominant form of the gene.

homosygous: having 2 like genes for a trait.

Heterozygous: of an organism which has two different alleles of a given gene

Punnett Square: a chart used to show all the ways genes from 2 parents can combine and be passed to offspring.
