(c) Based on the data in Table 1. describe why the dominant alleles for body color and wing shape are the alleles that produce a grav body and Jong wings, respectively. Based on the dala, describe why the two genes are most likely on different chromosomes or why they are most likely on the same chromosome, Calculate the probability of producing flies that have gray bodies and vestigial wings if a cross is performed between one of the F1 flies from the first analysis and a fly that is homozygous for a gray body and vestiglal wings. (d) Predict the most likely cause of the Fa ratio obtained by the students in the second analysis between parental flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings. Provide reasoning to justify your prediction. Students in a class are studying patterns of inheritance using genes involved in determining the body color and wing shape of Drosophila flies. Each of the genes has only two alleles, one of which is completely dominant to the other. Each student in the class performed a parental cross between a fly that is true-breeding for ebony body and vestigial wings and a fly that is true-breeding for gray body and long wings. Each student then crossed several pairs of the F1 flies and determined the phenotypes of 500 of the resulting F2 flies with respect to body color and wing shape. The students in the class averaged their data for the frequencies of the four possible phenotypes (Table 1). Table 1.
