When talking about types of genetic markers, the adjective "dominant" and "codominant" are often used. I don't fully understand their definitions and found contradicting definitions.
Foll and Gagiotti (2008)
Typically reading from Foll and Gagiotti (2008), they list give two examples of markers of each type
- Codominant markers
- Dominant markers
This reddit post indicates that RFLP are codominant markers (unlike stated in Foll and Gagiotti (2008)).
On wageningenur.nl (random website I never heard of before), they define dominant and codominant markers based on gene expression suggesting that the terms dominant and codominant used for markers have the same definition than those used for allelic effects on the phenotype (dominance, recessivity, overdominance, etc..).
What are the definitions of dominant and co-dominant genetic markers?
Can you please offer examples for each type and explain why they fit in one or another category?
Do the terms dominant and codominant have the same definition when used to describe a marker and when used to describe allelic effects on the phenotype (dominance, recessivity, overdominance, etc..)?
