A person with a genetic composition AA+XYY composition. The non-disjunction is in the __________ parent and in _____________ meiotic division. Correct Answer Male, 2nd

A female can never have Y chromosome to start with so the non-disjunction is in a male. If the non-disjunction was in 1st division improper segregation of X and Y will produce XY gamete. Here there is an improper 2nd division where 2Y generated in meiosis 2 moves to same pole giving YY gamete.
