Explain how the random alignment of homologous chromosomes during metaphase I contributes to variation in gametes produced by meiosis.
Figure 13.6 Which of the following statements about nondisjunction is true? Nondisjunction only results in gametes with n+1 or n-1 chromosomes. Nondisjunction occurring during meiosis II results in 50 percent normal gametes. Nondisjunction during meiosis I results in 50 percent normal gametes. Nondisjunction always results in four different kinds of gametes.

Adams maternal and paternal chromosomes have alternate forms of a gene that influences whether a person is right-handed or left-handed. One form says right and its partner says left. Visualize one of Adams spermatogonia, in which chromosomes are being duplicated prior to meiosis. Visualize what happens to the chromosomes during anaphase I and II. (It might help to use toothpicks as models of the sister chromatids of each chromosome.) What fraction of Adam's sperm will carry the gene for right-handedness? For left-handedness?
