The genes controlling the seven pea characters studied by Mendel are now known to be located on 4 different chromosome (1, 4, 5, 7) and not 7 chromosomes. Genes for seed colour and flower colour are located on chromosome 1. Genes for height, inflorescence and pod shape are located on chromosome 4. Gene for pod colour are located on chromosome 5. Gene for seed shape is located on chromosome 7.
Thus, the correct answer is option D.
