1. The frequency of multiple synonymous codons coding for the same amino acid is not equal in the genome. This is called:
(A) Post-translational modification
(B) Codon swapping
(C) Codon bias
(D) Four-fold degenerate sites

2. Although sometime pollination could successfully happen between different plant species, pollen-pistil incompatibility happens (the pollen from species A could not successfully germinate on the pistil of species B). This is a type of: (A) Premating barrier (B) Postmating prezygotic barrier (C) Postzygotic barrier (D) Hybrid incompatibility

3. Which of the following is a potential benefit for the evolution of sexual reproduction? (A) Facilitating the co-operation between parents (B) In theory, sexual reproduction produces twice the amount of progeny than asexual reproduction (C) Promoting male-male competition, facilitating the evolution of male traits (D) Combining alleles to generate new genotypes that might be adaptive to new environments

4. Which of the following about "secondary contact" in the model of speciation is true? (A) Results from vicariance (B) Results in allopatric speciation (C) Is caused by Dobzhansky-Muller incompatibility (D) Allele frequency cline is usually observed

5. In the famous example of the evolution of freshwater three-spined stickleback fish,the candidate gene Pitx1 does not express in the pelvic region, leading to the lack of development of pelvic spine. This is likely due to the mutation in which region of the Pitx1gene? (A) The enhancer or promoter region (B) The protein-coding region (C) The region under balancing selection in the lake
