Genetics 380: Spring, 2008 Problem Set # 8 ANSWER SHEET Q. 1. (a) Gene c + transferred first (starting at 5 minutes), gene b + second (starting at 10 minutes) and gene a + is transferred last (starting at 20 minutes). ______ a +_____ b +___ c + _____ > (b) a + d + colonies = 51/100 b + d + colonies = 8/100 c + d + colonies = 89/100 The parental combination of genes was a + b + c + d - (donor) and a - b - c - d + (recipient). The data above say that 8% recombination between gene d and gene b; 51% recombination between gene d and gene a ; and 89% recombination between gene d and gene c . Therefore, gene 'd' is closest to gene 'b' and closer to gene 'a' than gene 'c' . The map derived from these data is- The data don’t rule out the alternative map- _____a + _________b + __d - ___________c + _____ > 8 89 --------51------- Q. 2. The parental genetic combinations in the cross are arg + his + leu - and arg - his - leu +. . Due to the
