You obtain the following F2 phenotypes (where letters denote recessive phenotypes and pluses denote wild-type phenotypes: 1,400 ++ 400 ab 100 a+ 100 +b What is the recombination frequency between a and b? Remember that there is no recombination in male flies. Show your work. 20 m.u. 4. 8 points. A bacterium of a+ b+ c+ genotype is used as a donor in a transduction experiment using a P1 phage. The recipient strain was a- b- c-. Provide results in the table below that would be consistent with the following map, where a and b have a cotransduction frequency of 20 % and a and c have a cotransduction frequency of 10%. 
 a+ b- c- 70 10 % a+ b+ c- 20 % a+ b+ c+ 0 c
 % a+ b- c+ 10%.
