| Term | Definition |
|---|---|
| incomplete dominance | a condition in which neither allele for a gene completely conceals the presence of the other; it results in intermediate expression of a trait |
| codominance | the condition in which both alleles for a trait are equally expressed in a heterozygote; both alleles are dominant |
| heterozygous advantage | a survival benefit for individuals who inherit two different alleles for the same trait |
| continuous variation | a range of variation in one trait resulting from the activity of many genes |
| polygenic trait | a trait that is controlled by more than one gene |
| linked genes | genes that are on the same chromosome and that tend to be inherited together |
| sex-linked trait | a trait controlled by genes on the X or the Y chromosome |
| bioinformatics | a field of study that deals with using computer technology to create and analyze large databases of information |
| genomics | the study of genomes and the complex interactions of genes that result in phenotypes |
| genetic profile | the complete genotype of an individual, including various mutations |
