E o C Biology Review 4: Genetics, DNA, & Protein Synthesis

Which of the following is NOT one of Gregor Mendel's principles?

• The alleles for different genes usually segregate independently
• Some forms of a gene may dominant
• The inheritance of characteristics is determined by factors (genes)
• Crossing-over occurs during meiosis
