Textbook Question
Chapter 11, Problem 1S
Diagram the process of meiosis for an imaginary cell with six chromosomes in a diploid cell.
a. How many homologous pairs are present in this cell? Create a drawing that distinguishes between homologous pairs.
b. Label each homologue to indicate whether it is maternal (M) or paternal (P).
c. Draw a new cell showing how these chromosomes would arrange themselves during metaphase of meiosis I. Do all the maternal homologues have to line up on the same side of the cell?
d. How would this picture differ if you were diagramming anaphase of meiosis II?

- Consider a diploid cell that has 2n = 4 chromosomes: one pair of metacentric chromosomes and one pair of acrocentric chromosomes. Suppose that this cell undergoes nondisjunction, giving rise to an autotriploid cell (3n). The triploid cell then undergoes meiosis. Draw the different types of gametes that could result from meiosis in the triploid cell, showing the chromosomes present in each type.
