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. P2 SS White. Plum kernel P1 Genotype. Phenotype: Red, shrunken kernel RRSS F1 Testcross Genotype: Phenotype: RISS Red, plum kernel White, shrunken kernel F2 Red, plump Red, shrunken White, plump White, shrunkend 121 3420 3335 124 c) Compute the distance between the two genes using the formula below: Total Number of Crossover Types Linkage value (LV) = x 100 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)
