I'm guessing that's why some of the SPY's dividends are unqualified. Page 34 of the same website contains the tax information for the DIA. The DIA paid $2.93 a share in 2008, all of which is qualified.
The mutated gene is passed down through a family, and each generation of children can inherit the gene that causes the disease. Rarely, one of these monogenic diseases can occur spontaneously in a child when his/her parents do not have the disease gene, or there is no history of the disease in the family.
In single-gene diseases, a mutation in just one of these genes is responsible for disease. Single-gene diseases run in families and can be dominant or recessive, and autosomal or sex-linked.Pedigree analyses of large families with many affected members are very useful for determining the inheritance pattern of single-gene diseases. Table 1 includes some examples of single-gene diseases.ingle-gene diseases run in families and can be dominant or recessive, and autosomal or sex-linked.
