Mendel showed that flower position (side vs top) and pod shape (inflated vs constricted) each behaved as single-locus Mendelian traits. The flower position locus is not linked to the pod shape locus. When Mendel crossed homozygous side-flower inflated-pod peas to homozygous top-flower constricted-pod peas, What was the ratio of the F1 generation?
