In a Cotransduction Experiment the Alleles A+, B+, and C

question 28

Multiple Choice

In a cotransduction experiment the alleles a+, b+, and c+ were studied. The allele a+ alone was transduced into an auxotroph 1750 times, b+ alone 1700 times, and c+ alone 1725 times. Alleles a+ and b+ were both found 11 times, b+ and c+ 117 times, and a+ and c+ 15 times. What can you definitely conclude?

• A) Genes b and c are more closely linked than a and b or a and c.
• B) The genes are all located extremely close to each other.
• C) Genes b and c are found together only if double crossovers have occurred.
• D) The gene order is a, b, c.
• E) Genes a and b are more closely linked than a and c or b and c.
