Short Tandem Repeat (STR) loci, are assumed to be in Hardy-Weinberg equilibrium in large human populations. Why is this a generally reasonable assumption? (select all that apply)

The diagram below illustrates the gene editing procedure, based on the CRISPR-Cas9 system in bacteria.  Where you see “N”s, that means DNA bases (A, C, G or T) that are not specified precisely here).    Match the identity of the components (A, B and C) with list of possibilities given.  Not all possibilities will be used!

Briefly explain and/or show your calculations for the expected HW equilibrium genotype frequencies in the previous question.

When done, submit your answers. Before leaving the classroom, sign out with an instructor or TA and turn in any scratch paper.
