1. In fruitflies, scarlet eyes (s) is autosomallyrecessive to wild-type color; ebony body is autosomally recessiveto wild-type body. The traits are located on the 3rdchromosome & are 26 cM apart. A wild-type female istest-crossed (see cross below). Based upon the information given,complete the chart.
