8. Which of the following maps and conclusions best fits these results? \\[ \\text { a.sma-12 - } 1 \\text { mu - unc- } 23-3 \\text { mu - T/A. } \\] i. \\( s m a-12 \\) is left of \\( u n c-23 \\) by \\( 1 \\mathrm{mu} \\). b. ync. \\( 23-3 m u-T / A-1 \\) mu-sma-12. i. sma- 12 is right of the \\( \\mathrm{I} / \\mathrm{A} \\) locus by 1 mu. c. unc. \\( 23-1 \\mathrm{mu}-\\mathrm{sma}-12-2 \\mathrm{mu}-\\mathrm{T} / \\mathrm{A} \\). i. sma- 12 is between unc-23 and the T/A locus, ii. 1 mu right of the unc-23 locus. d.unc- \\( 23-2 m u-s m a-12-1 m u-T / A \\). i. sma- 12 is between unc-23 and the T/A locus, ii. 2 mu right of the unc-23 locus. 9. Therefore, what can you learn from three-factor mapping that you couldn't from two-factor mapping
