Extracted text: You are trying to determine the relative positions of three genes (A, B and C) that are thought to be on the same chromosome of the organism. You do two dihybrid testcrosses with A being checked in both crosses (so A and B are the genes in one cross and A and C are the genes in the other cross). Based on the results below, which gene (B or C) is closer to A? How can you tell? AаBb aabb Aabb aaBb Total 300 299 202 199 1000 AaCc aacc Аасс aaCc 475 477 25 23 1000
