Academics

You coinfect an E. coli strain with 2 strains of phage T4 phage(virus). One strain is m r tu and the other strain is wild type (m+ r+ tu+). The progeny phages fromthis cross are plated and classified according to their genotypes. The results are shownbelowm
r tu     3352 m + + 503
+ + + 3606        + rtu   458
m r +    825       + r+    166
m + tu   157 + + tu   933 Total = 10,000
a. Determine the 3 map distances (m-r, r-tu, and m-tu).
b. Make a genetic map.
c. What is the coefficient of coincidence? What is theinterference? What does it tell you about 2 nearby crossovers in phages that is different from that ineukaryotes?
