Haploid

Gametes: These are sex cells (like sperm and egg) that are haploid, meaning they contain only one set of chromosomes.

Meiosis: This is the process by which diploid cells divide to produce four haploid cells, each with half the number of chromosomes as the parent cell.

Monosomy: This is a condition in which an organism or cell has one less chromosome than usual - it's like missing an ingredient from your cookie recipe!
