A single autosomal gene with two alleles determines whether you have attached earlobes or free-hanging earlobes. X-linked traits are those controlled by an allele that is carried on the X chromosome, while autosomal traits are controlled by alleles located on any chromosome excluding the X or Y. Color blindness is an X-linked recessive trait. That relatively pure metal is either used in various products or purified further. The inheritance pattern that allows only one trait to show is called _____ _____.

Patterns of Inheritance | Anatomy and Physiology II - Lumen Learning Genetic inheritance controls the characteristics of all living things. Of note, ethnic differences in the frequency of lobe attachment are well documented, 6 suggesting that genetic heterogeneity might underlie the trait and that deciphering its genetic architecture might require trans-ethnic studies.
