Fruit flies with one allele for curly wings (cm and one allele for normal wings (cy+) have curly wings. when two curly- winged flies were crossed, 203 curly-winged and 98 normal-winged flies were obtained. in fact, all crosses between curly- winged flies produce nearly the same curly : normal ratio among the progeny. a. whet is the approximate phenotypic ratio in these offspring? b. suggest an explanation for these date. c. if a curly-winged fly was mated to e normal- winged fly. how many flies of each type would you expect among 180 total offspring?
