9. (2pts) During one round of meiosis in a human male, a single non-disjunction event occurs in meiosis that affects only chromosome 1. What are ALL the possible gametes produced from this one round of meiosis? (NOTE: in the answers '1' represents a single chromosome 1 chromatid, 'O' indicates no chromosome 1 chromatid; 'X' represents a single X chromatid, 'Y' represents a single y chromatid, each dash indicates separation between each gamete. 1X - 1X - 1Y - 1Y 11X...
