For each question, select the best answer from the four alternatives. 1. Which of the following processes increases diversity in a population? (4.1, 4.2) K/U (a) sexual reproduction (b) asexual reproduction (c) cell division (d) fragmentation
2. Prior to cell division, the original chromosome and the duplicate it is attached to are called (a) chromatin (b) centromeres (c) genes (d) sister chromatids (4.2) K/U
3. In male mammals, meiosis results in the formation of (a) one haploid gamete (b) one diploid gamete (c) four haploid gametes (d) two diploid gametes (4.3) K/U
4. Each parent passes on to its offspring only one of its two alleles for a gene. What is this phenomenon called? (a) dominance (b) codominance (c) the law of segregation (d) the law of independent assortment (5.1) K/U
5. Which of the following procedures is an example of assisted reproductive technology? (4.4, 6.2, 6.3) K/U (a) transposition (b) laser-assisted hatching (c) DNA fingerprinting (d) all of the above

Figure 1 Image: Illustration of a cube broken into four equal parts to show the dominance of a trait such as coloring between a white cow and a red bull should they have offspring which color those offspring might be due to genetic possibilities.
9. Which of the following options is a correct complementary base pair of DNA? (6.1) K/U (a) adenine and thymine (b) cytosine and thymine (c) guanine and adenine (d) guanine and thymine
Match each term on the left with the most appropriate description(s) on the right.
