This hypothetical pedigree for a disease in humans illustrated inheritance that is

Autosomal recessive

Explanation:

Autosomal recessive is the genotypic type of expression of traits. In an autosomal recessive disorder, 2 copies of an abnormal gene must be present which are responsible for the development of the trait.

The parents of the individual that have an autosomal recessive each must carry a copy of a mutated gene or deffected or abnormal gene but they do not show signs and symptoms of the condition. The autosomal recessive disorders are not seen in every generation of the family which is affected.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
