• Karyotype: A karyotype is a picture of chromosomes arranged in pairs. This is a standard definition in genetics.
• Sex chromosomes: These are the chromosomes (like X and Y in humans) that determine an individual's sex.

• Pedigree: A pedigree is a chart that shows the relationships within a family, often used in genetics to trace traits.
• Sex - linked gene: A sex - linked gene is located on the X or Y chromosome.
• Nondisjunction: Nondisjunction is the failure of homologous chromosomes to separate in meiosis.
