What is the difference between Mendelian and polygenic traits?  If 100 adult men stood in a line, how could you tell, just by looking, that human height is a polygenic trait?

What is the difference between Mendelian and polygenic modes of inheritance? Why are most human traits polygenic? How do we know that human height is a polygenic trait? (and don't say because it is coded by more than one pair of alleles)

22. Which of the following statements about polygenic traits and Mendelian traits are CORRECT? i. Polygenic traits are rarely involved in adaptation. ii. Mendelian traits commonly show discontinuous variation. iii. Polygenic traits are more strongly influenced by the environment. iv. Mendelian traits are usually governed by a small number of genes. a. i, iv b. ii, iii, iv c. i, ii, iii d. ii, iv

. Consider the alleles involved in polygenic traits such as human height. Is the concept of dominance relevant to these alleles? Why or why not? A. Yes-- the dominant trait alleles confer the highest values for the trait and the highest fitness. B. Yes—The dominant alleles are the most common C. No—the alleles in polygenic traits are always co-dominant D. No—dominance can occur only in discrete traits.
