In an imagined transduction experiment with alleles a⁺, b⁺, and c⁺, a⁺ alone was transduced into an auxotroph 1400 times, b⁺ alone 1200 times, and c⁺ alone 970 times. Genes a⁺ and b⁺ were both found 10 times, b⁺ and c⁺ 2 times, and a⁺ and c⁺ one time. What can you conclude? A)Cotransduction is too infrequent to be used to map genes. B)Genes a and c cotransduce only accidentally. C)Genes a and b are more closely linked than a and c or b and c. D)Genes a and c are found together only if double crossovers have occurred. E)Transduction of gene c is very rare.

Genes a and b were found together more frequently (10 times) than a and c (1 time), or b and c (2 times). This suggests that genes a and b are more closely linked and are more likely to be cotransduced than a and c or b and c.
