In Drosophila, yellow bodies (y) and white eyes (w) are both caused by recessive X-linked alleles. The normal alleles (y* amd w*) cause tan bodies and red eyes, respectively. A yw female is mated to a y* w* male and the F₁ progeny are allowed to mate with each other. Two hundred F2 were observed and they are: 55 yw; 45 y w*; 45 y* w; 55 y* w*. What is the chi-square value for the test for goodness of fit of the null hypothesis of no linkage? (Recall that the chi- square statistic is the sum, for all classes, of (O-E)²/E.) O ● 10 0.5 20 1.0 0.4 2.0
