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 Genetics of Blood Type Â©2006 Blood type is an example of a trait determined by a single gene. Each of us has two copies of the gene for blood type on chromosome pair number 9.One copy is inherited from our mother, the other from our father.here are three versions (called âallelesâ) of this gene: A, B, and O. A personâs blood type is determined by which allele he/she inherits from each parent. The genetic constitution of an organism is called the âgenotypeâ.
