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
