111 Problems a. Metaphase of mitosis b. Metaphase I of meiosis c. Telophase of mitosis d. Telophase I of meiosis e. Telophase II of meiosis 26. Four of the following events are part of both meiosis and mitosis, but one is only meiotic. Which one? (1) Chromatid formation, (2) spindle formation, (3) chromosome condensation, (4) chromosome movement to poles, (5) synapsis. 27. Suppose you discover two interesting rare cytologi- cal abnormalities in the karyotype of a human male. (A karyotype is the total visible chromosome com- plement.) There is an extra piece (or satellite) on one of the chromosomes of pair 4, and there is an abnormal pattern of staining on one of the chromo- somes of pair 7. Assuming that all the gametes of this male are equally viable, what proportion of his children will have the same karyotype as his? 28. Suppose that meiosis occurs in the transient diploid stage of the cycle of a haploid organism of chromo- some number n . What is the probability that an in- dividual haploid cell resulting from the meiotic
