The nitrogen oxides are not all bad. They are both used in the lead chamber process as catalysts to convert SO2 to SO3, which is the essential first step in the production of sulphuric acid. They are also precursors in the Ostwald Process for the manufacture of nitric acid (see below).
Single Gene Traits in Humans. The following is a list of some autosomal human traits that have been attributed to a single gene. Although clearly other genes are involved, the inheritance of each of these phenotypic traits acts as if it were governed by a single gene. First, indicate your expression of the trait (i.e., circle the appropriate phenotype).

The first 22 pairs are autosomes whereas the 23rd pair are the sex chromosomes (X and Y in males or X and X in females). A trait is a characteristic determined by genes. An autosomal trait will therefore be determined by a gene on an autosomal chromosome whereas a sex linked trait will be determined by a gene on one of the sex chromosomes.
