Question:
How would you describe Mendel's laws in generating expected values for the Chi Square analysis? What if the traits that were being tested are linked rather than independently assorted, would be still be able to use Mendel's Laws in generating expected values?


Replies:
By definition, Mendel's 2nd Law, the Law of Independent Assortment (Segregation), does not apply to genes that are linked to the same chromosome. The expected ratios in such a cross can only be calculated if the recombination frequency for a pair of loci is known from previous crosses
