The DD genotype gene is a linkage marker for an etiologic mutation at or near the angiotensin-converting enzyme gene and has been associated with increased risk for the development of coronary artery disease, left ventricular hypertrophy and left ventricular dilation after myocardial infarction.

Is DD dominant or recessive?

In genetics, the dimple version of a gene is D and the non-dimpled version is d. Remember, we have two copies of most of our genes, one from mom and one from dad. You will have dimples if both copies are D (DD) or if only one is D (Dd). That is the definition of dominant.

What is FF genotype?

Genotype is the genetic makeup of an individual eg Ff or FF. Phenotype is the physical appearance eg carrier of cystic fibrosis. ... A Recessive allele only has an effect if you inherit two copies eg ff (cystic fibrosis). If two carriers have children, each child has a 25% of being born with the disease.
