The first photo is the procedure while the other photo is the problem that needs to be answered. Please answer correctly, and provide proper solutions and explanations from A to E. Thank youuuu

Procedure
1. Linkage involving two genes using the data on corn kernel shape (Gene R) and color (Gene S).
a) Assess the F2 progenies if they follow the 1:1:1:1 segregation pattern after the testcross
procedure using the chi-square test.
b) Identify the cause of the different segregation patterns. Write your answer under the
conclusion.

c) Compute the distance between the two genes using the formula below:
Total Number of Crossover Types y 100
Linkage value (LV) = Total Number of the Population
d) Make a linkage map indicating the linked genes and the distance between the genes.
Note: 1% LV = 1 map units or centiMorgan (cM)
