The Chromosomal Theory of Inheritance is consistent with Mendel's laws in all of the following observations EXCEPT: a During meiosis, homologous chromosome pairs migrate as discrete structures and are independent of other chromosome pairs. b Gametic chromosomes combine during fertilization to produce offspring with the same number of chromosomes as their parents. c The sorting of chromosomes from each homologous pair into pre-gametes is never random. d Each parent synthesizes gametes that contain only half of their chromosomal complement.
