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 |
