Passage VI
In the yeast Saccharomyces cerevisiae, the function of meiosis is to divide a diploid cell into 4 haploid cells called spores. During meiosis, the 2 copies of a chromosome, or homologs, undergo DNA replication (when each homolog becomes a linked pair of sister chromatids) followed by 2 rounds of chromosome segregation (separation into different cells) called Meiosis I and Meiosis II. The figure shows the homologs of a particular chromosome during meiosis in a wild-type S. cerevisiae strain and also in 2 mutant S. cerevisiae strains (Mutant A and Mutant B) each having a different mutation that affects meiosis.
36. According to the figure, does meiosis in the Mutant B S. cerevisiae strain produce as many spores as does meiosis in a wild-type S. cerevisiae strain?
Your Answer is
Correct Answer is F
Explanation
Looking at the Note below the picture in the text, we can see that every cell produced after Meiosis II is called a spore, so the wild-type strain produced 4 spores, while the Mutant B strain produced 2 spores
