Sex Chromosome

Real World Example

Imagine you're sorting through a deck of cards to find the joker card that determines the game's wild card rules. Just like the joker card sets the rules for what can be played in the game, sex chromosomes determine an individual's sex. In this analogy, the deck of cards represents the complete set of chromosomes, and the joker card is akin to the sex chromosome; it’s the one card, or chromosome, that establishes the overall rule or trait—in this case, whether an individual is male or female.
