In fruit flies, strаight wings (S) is dоminаnt tо curved wings (s). Recently, yоu hаve discovered a new gene in flies that exists in two alleles. The allele designated L causes large heads and the l allele causes small heads. These genes are autosomal and follow a Mendelian pattern of inheritance. You begin with two true-breeding strains, straight wings with small heads and the other curved wings with large heads. All of the F1 offspring have straight wings with large heads. You then cross the F1 offspring to flies with curved wings and small heads and obtain the following results. 187 Straight wings, small heads 60 Curved wings, small heads 197 Curved wings, large heads 56 Straight wings, large heads 500 Total F2 offspring Note: TABLE 2.1 Chi Square Values and Probability Degrees of Freedom P ∙ 0.99 0.95 0.80 0.50 0.20 Null Hypothesis Rejected 0.05 0.01 1 0.000157 0.00393 0.0642 0.455 1.642 3.841 6.635 2 0.020 0.103 0.446 1.386 3.219 5.991 9.210 3 0.115 0.352 1.005 2.366 4.642 7.815 11.345 4 0.297 0.711 1.649 3.357 5.989 9.488 13.277 Conduct a chi square analysis on these data.
