In the following table record the likelihood of producing a zygote with the various sex aneulploidies due to a single non-disjuction (ND) event.
Make sure your answer is recorded as a PERCENTAGE (fractions or decimal places are not permitted).
You are to assume that meiosis continues in the other parent normally (i.e. there will be no double non-disjunctions). Further, if a nondisjunction occurs during Meiosis I, you are to assume the Meiosis II continues normally and vice versa.
Make sure that your answer is only a number. Written words, punctuation marks or the inclusion of the percentage sign, will result in your answer being recorded incorrect.
