Bio 130 – Quiz March 26

Privet chromosomes undergo only mitosis. Q. 1 - Privet shrubs and humans each have a diploid number of 46 chromosomes per cell. Why are the two species so dissimilar? Privet chromosomes undergo only mitosis. Privet chromosomes are shaped differently. Human chromosomes have genes grouped together differently. The two species have appreciably different genes. Privets do not have sex chromosomes. Answer: d

Q. 2 - In this cell, what phase is represented? mitotic metaphase meiosis I anaphase meiosis I metaphase meiosis II anaphase meiosis II metaphase Answer: c (see Figure 13.9)

Q. 3 - How and at what stage do chromosomes undergo independent assortment? meiosis I pairing of homologs anaphase I separation of homologs meiosis II separation of homologs meiosis I metaphase alignment meiosis I telophase separation Answer: d
