Refer to the drawings in Figure 13.2 of a single pair of homologous chromosomes as they might appear during various stages of either mitosis or meiosis, and answer the following questions (28). Which diagram represents chromosomes in prophase I of meiosis? I II III IV V VI Which diagram represents anaphase II of meiosis? I III IV V

Solution

26) IV

Explanation: During prophase I of meiosis, synapsed homologous chromosomes are observed as tetrads.

27) II

Explanation: There is separation of centromeres. As a result, chromatids separate and they are now called independent chromosomes.
