The maize genes S (s⁺ , s alleles) and B ( b⁺ , b alleles) are linked, 40 map units apart. If a doubly heterozygous plant with genotype s⁺ b / s b⁺ is self fertilized, what proportion of the progeny will be homozygous s b / s b ?

a. 0.40 b. 0.20 c. 0.50 d. 0.10 e. 0.04

I need this simplified and to find the type of reaction:

1. What is the equation associated with Avogadro's Hypothesis?

Compare Solution A and Solution B in each label and drag the label to the appropriate concentration description.

 Suppose you have two A-B-type exotoxins, A-B and A’-B’. A-B binds specifically to all

MHC-II cells and blocks vesicle trafficking. A’-B’ binds specifically to all MHC-I cells and

stops protein synthesis.

a. What would a hybrid toxin, A’-B, do to fibroblast (skin) cells? Provide your rationale.

b. What would a hybrid toxin, A-B’, do to fibroblasts? Provide your rationale.

c. What would a hybrid toxin, A’-B, do to macrophages? Provide your rationale.

d. What would a hybrid toxin, A-B’, do to macrophages? Provide your rationale
