Which of the following statements about Mendelian of colfpiex O Mapping of quantitative trait loci does relies on genetic variations that directly contribute to the trait of interest. Genetic methods for studying Mendelian phenotypes, such as crossing, is not useful for mapping quantitative trait loci. Genetic factors determine Mendelian traits, while environmental factors determine complex traits. Both Mendelian and complex traits are associated with single gene locus. Genome-wide assocint
