6. If the percent G + C content of a DNA molecule is 34%, then what are the percentages
of the four individual bases (A,T,G and C) (1 mark)?
%A=33 %T=33 %G=17 %C=17

1a.
Cb

Ge---------Cb---------St
      7.1          7.1

Interference = 1 - Observed DR/Expected DR
1 - 6/5.041 = -0.19024

Not sure.  Go with what you think  It's one or the other.  Just can't think of if it's forward or backward.

For #2a:
+++ is missing because those are the females who are unaffected
2b:
bac

That's all I got.  Good luck.

a.
Cb

b.
Ge-Cb
(46+43+6)/1000 = 0.095 * 100 = 9.5 mu

Cb-St
(22+19+6)/1000 = 0.047 * 100 = 4.7 mu

Ge----------------------Cb-----------St
           9.5 mu          4.7 mu


c.
Observed double recombinants: 6
Expected double recombinants: (0.095)(0.047) = 0.004465*1000 = 4.465
Interference = 1 - 6/4.465 = -0.34378
