In humans, if a non-disjunction event led to an individual with a genotype of XXY, they would be male because they have a Y chromosome.
<h3>What are X and Y chromosomes?</h3>
The X chromosome and Y chromosome are homo-logous chromosomes that determine the se_x in mammals.
The presence of the Y chromosome is indicative of the males, whereas two X chromosomes are females in normal conditions.
Non-disjuntion refers to the faulty separation of homo-logous chromosomes during meiosis.
