An unusuаl phenоtype in Drоsоphilа is singed bristles. Flies with singed bristles look like they hаve survived an encounter with a blowtorch! A geneticist first created a purebred culture of flies with singed bristles and then bred those flies with a purebred culture of wild flies (with normal bristles). In the F1 generation, all flies had normal wild-type bristles. When the F1 flies were allowed to mate among themselves, the following F2 generation was produced: 70 flies with singed bristles and 166 flies with normal bristles. Determine a proposed inheritance of singed bristles and analyze the F2 data using chi-square (X2, chi-square) analysis.
