The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust d
Dennis_Churaev [7]

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.
