Some key Mendelian traits in domesticated plants. (A) Early genetic work in plants focused on maize, including various kernel traits, such as aleurone and pericarp color.

(B) Glutinous phenotype caused by mutations at the Wx gene leads to sticky rice valued by cultures in Northeast and Southeast Asia. (C) The round vs. (D) wrinkled pea phenotype maps to the r allele first described by Mendel, with the latter caused by a 0.8-kb TE insertion into a starch branching enzyme gene.
