Sample questions:
•According to Boyd and Silk, stabilizing selection tends to prevent traits of organisms changing over time.
- True
- False
•All of the following are true of the relationship between DNA and proteins EXCEPT:
- a sequence of three DNA base-pairs codes for one amino acid
- a single codon codes for one amino acid
- an amino acid is coded by only one codon
- sequences of codons code for sequences of amino acids
•A primitive trait is one that was inherited from a common ancestor and was replaced because it was poorly adapted to local conditions.
- True
- False
•If we found that a species of primate has little to no sexual body dimorphism, what might we infer is the most likely mating system of this species?
- Monogamous, pair bonded
- Multi-male, multi-female
- One-male, multi-female
- One-female, multi-male
•According to Boyd and Silk, independent segregation only occurs for traits controlled by genes on different chromosomes?
- True
- False
