Seems like B to me.

Not A because 0.2 * (1-0.2) = 0.16

Certainly not somatic mutation and variable expressivity.

Well, yea, i also put the answer B, but i think that right answer is A. Look up Kaplan in Genetics section - Linkage Disqulibrium. And plz, explan me - what is random assorsment. I found it only in microbial genetics , and it doesn`t fit here

linkage equilibrium makes most sense....since the expected probability of both alleles together is 0.2 *0.2 = 0.04 or 4% but since they appear together at 16% they must be linked and so linkage disequilibrium. Random assortment i think just means when in miosis homologous chromosomes are randomly segragating into different gametes.
