While it is often convenient to talk about a recessive allele or a dominant trait, dominance is not inherent to either an allele or its phenotype. Dominance is a relationship between two alleles of a gene and their associated phenotypes.

1) What is my fuel/oil ratio? Johnson and Evinrude carbureted 2-stroke outboards since 1964 require a 50:1 fuel to oil mixture (2%) on engines without an automatic oiling system â 6 gallons of gas to 1 pint of outboard oil. Refer to question #5 for information on oil. Most outboards manufactured before 1964 need 24:1.
