• The sperm cell is a heterogamete that carries either an X or Y chromosome.
• Heterogametes are essential for sexual reproduction and genetic variation.
• During meiosis, heterogametes of different types are generated to ensure genetic diversity.
• The egg and sperm are heterogametes that combine to form a zygote.
