You say tomato The paper “Linkage Studies of the Tomato” (Transactions of the Canadian Institute, 1931) reported the following data on phenotypes resulting from crossing tall cut-leaf tomatoes with dwarf potato-leaf tomatoes. We wish to investigate whether the following frequencies are consistent with genetic laws, which state that the phenotypes should occur in the ratio 9:3:3:1.

Phenotype: Tall cut Tall potato Dwarf cut Dwarf potato Frequency: 926 288 293 104 Assume that the conditions for inference were met.

Carry out an appropriate test of the proposed genetic model. What do you conclude?
