p. 312 A.Q. 1abc, 2a1a. What did Mendel conclude determines biological inheritance?1a. Mendel concluded that factors that are passed on from one generation to the next determines biological inheritance.

1b. What are dominant and recessive alleles?1b. A dominant allele is the form of an allele whose trait always shows up if it is present. A recessive allele is the form of an allele whose trait shows up only when the dominant allele is not present.

p. 312 A.Q. 1abc, 2a1c. Why were true-breeding pea plants important for Mendel’s experiments?1c. True-breeding pea plants were important for Mendel’s experiments because they have two identical alleles for a gene. In a genetic cross, each parent contributes only one form of a gene, making inheritance patterns more detectable.

2a. What is segregation?2a. Segregation is the separation of alleles.
