A three point test cross was carried out in Drosophila melanogaster involving three adjacent incomplete link genes A, C and B arranged in the same order. The distance between A to C is 20 map units (mu) and that between B to C is 10 map. If pure line Drosophila AAbbCC crosses with aaBBcc to produce F1 offspring were allowed to cross with aabbcc result in 1000 offspring, which of the following genotype combination with number is correct?
