Ch 11.1 Assessment 1. What did Mendel conclude determines biological inheritance? 2. What are dominant and recessive alleles? 3. Why were true-breeding pea plants important for Mendel’s experiments? 4. What is segregation? 5. What happens to alleles between the P generation and the F2 generation? 6. What evidence did Mendel use to explain how segregation occurs? 7. Use a diagram to explain Mendel’s principles of dominance and segregation. Your diagram should show how alleles segregate during gamete formation.
