If a A/A*B/B is crossed with a/a*b/b and the F1 is testcrossed, what percentage of the test cross progeny if they're:
a) unlinked
b) linked
c) 10 mu
d) 24 mu
a) each would have a 25%
b) only parentals with a 50%
c) parents would have 45% each
d) parents would have 38% each
In a haploid organism, cD x Cd are crossed. C and D are 8 mu apart. what proportion will be:
a) CD
b) cd
c) Cd
d) all recombinants
a) 4
b) 4
c) 46
d) 8
+/+*+/+*+/+ x p/p*v/v*b/b
a) linked?
b) map
a) all 3
b) v-----p---b
v->p 22
p->b 15
ignore d and f
a) 1:1:1:1 ratio
b) 0.76
c) 3 df; p is between .5-.9
e) accept
yes all 3
al------18.1---fu----4.8---b
a) F1 would have all dominant
b) t---------D ; w----------A and T----------d ; w---------A
F1 would be same
c) 0.52
