Drosophila females heterozygous for 3 recessive mutations a, b, and c were crossed to males homozygous for all 3 mutations. The cross had the following results: wild 75 c 348 ab 306 b 96 ac 110 abc 85 Based on their recombination frequencies, the map distances in cM among the 3 alleles are? a-b ; b-c ; a-c?
