autosomal dominant
defined: A gene on one of the autosomes that, if present, will almost always produce a specific trait or disease. The chance of passing the gene (and therefore the disease) to children is 50-50 in each pregnancy.

Dominance relationship
- For other non-genetic uses of the term "dominance", see Dominance.
There are three main kinds of dominance relationships:
- Simple dominance or complete dominance (simple Mendelian inheritance) over a recessive trait
- Incomplete dominance
- Codominance
In general terms, a gene contributes to production or expression of some trait or character (a phene), e.g. the color of one's iris. A locus is similar, but more loosely defined: since phenes are usually readily apparent but determining which genes contribute to them is a complicated process, loci are simply locations in the genome which are known to be directly related to expression of defined phenes. Most loci can eventually be assigned to specific genes, but there is no straightforward 1:1 relationship between loci and genes, and whereas a gene always encodes for a protein, a locus might be in a noncoding DNA sequence.
