Yоu perfоrm а dihybrid crоss to determine if two genes thаt determine fruit fly wing shаpe and eye color are not linked (independent assortment on different chromosomes). Assume no crossover. Note: normal wings are dominant and down-curved wings recessive; red eyes are dominant and maroon eyes are recessive. You begin by crossing true breeding parents for both traits. You then self-cross your F1 generation and observe the following phenotypes in the F2 generation: 218 normal wings, red eyes 70 normal wings, maroon eyes 74 down-turned wings, red eyes 26 down-turned wings, maroon eyes Perform a Chi-squared test on the data. Provide your calculated Chi-square value and the degrees of freedom in the table below; show your work by reproducing the table (5x5). State the hypothesis being tested. Should the hypothesis be accepted?
