B) I^A/I^B for the female and I^A/i for the male. C) I^A/I^B/i for the female and I^A/I^A for the male. D) I^A/I^B for the female and I^A/i for the male. E) None of the combinations above. 27. A line of fruitfly is paracentric inversion heterozygote with a pair of homologous chromosomes that look like this: Normal: A(centromere)BCDEFG Inverted: A(centromere)bCFeDg The B and C loei are 5 map units apart. Predict the recombination frequency between B and C in the gametes of this line of fruitfly. (For simplicity's sake, only consider single crossing-overs.) A) 5% B) less than 5% but impossible to know the exact percentage C) more than 5% D) 2.5% E) 0% The E and F loci are 7 map units apart.
