Basic Genetic Terms- O'neill

Any specific, true-breeding property of an organism. Synonymous with "trait" or "phenotype"

A linear end-to-end arrangement of genes and other DNA, sometimes associated with proteins and RNA

Trait for which there is an unbroken range of phenotypes (i.e. continuous variation)

A cross between two individuals with different alleles at two gene loci

Two variants of one gene determine two contrasting discrete phenotypes for a specific trait

A eukaryote cell or organism having two sets of chromosomes (or a pair of genes at each locus)

A character is found in a population in two or more distinct and separate forms (phenotypes)

An allele or trait that expresses its phenotype when heterozygous with a recessive allele

An organism or cell that is diploid for each character, where the entire genetic complement is contained within a well-defined nucleus.

Are 1N and have no defined nucleus

The progeny of a cross between two parental types that differ in one or more genes

A haploid reproductive cell such as a sperm and egg

The basic unit of heredity that occupies a fixed chromosomal location (locus). Holds information for trmRNAs (proteins) and non-coding RNAs

The entire complement of genetic material in a chromosome set

The molecular characterization of entire genomes
