You are studying cushion plants in New Zealand: the wild-type cushion plan has a wide canopy. You obtain eight cushion plants that all have narrow canopies caused by a single autosomal recessive mutation. To determine how many genes are defined by these mutations, you mate the plants together and get the results shown in the complementation table below.  The “–“ represents plants with narrow canopies and the  “+” represents wide canopies. What will the offspring of a cross between plants A and F look like?

Question

a) You are studying cushion plants in New Zealand: the wild-type cushion plan has a wide canopy. You obtain eight cushion plants that all have narrow canopies caused by a single autosomal recessive mutation. To determine how many genes are defined by these mutations, you mate the plants together and get the results shown in the complementation table below.  The “–“ represents plants with narrow canopies and the  “+” represents wide canopies. What will the offspring of a cross between plants A and F look like?

b) Based on the above, how many different genes are defined by the 8 mutant strains?

This table is a grid comparing elements labeled A through H with each other, using positive (+), negative (−), or unknown (?) symbols to denote relationships or interactions between them.

- **First Row (A):** 
  - A with B: − 
  - A with C: − 
  - A with D: + 
  - A with E: + 
  - A with F: + 
  - A with G: ? 
  - A with H: +

- **Second Row (B):** 
  - B with C: − 
  - B with D: + 
  - B with E: + 
  - B with F: − 
  - B with G: + 
  - B with H: +

- **Third Row (C):** 
  - C with D: − 
  - C with E: + 
  - C with F: + 
  - C with G: + 
  - C with H: −

- **Fourth Row (D):** 
  - D with E: − 
  - D with F: + 
  - D with G: − 
  - D with H: +

- **Fifth Row (E):** 
  - E with F: − 
  - E with G: + 
  - E with H: +

- **Sixth Row (F):** 
  - F with G: − 
  - F with H: +

- **Seventh Row (G):** 
  - G with H: −

This table can be utilized for analyzing the comparative attributes or interactions among the elements. The presence of a question mark indicates uncertainty or a lack of data concerning the interaction between A and G.
