In the shepherd's purse, Capsella bursapastoris, the capsule containing the seeds can be either triangular or ovoid. A cross between certain true-breeding strains with triangular capsules yielded an 11eb71fd_c943_f2cb_a6e4_7d582c72e4ac_SM1238_11 generation with triangular capsules. The observed 11eb71fd_c944_19dc_a6e4_797485de2e7f_SM1238_11 ratio was 15 triangular : 1 ovoid. What genetic hypothesis can explain these results? What crosses would you carry out to test this hypothesis?
