* Simple explanation: "A person's genotype refers to their genetic makeup, which determines their inherited traits."
* Specific example: "The genotype of a pea plant can be homozygous dominant (RR) for round seeds, homozygous recessive (rr) for wrinkled seeds, or heterozygous (Rr) for round seeds."
* In contrast to phenotype: "While the genotype determines a person's genetic potential, their phenotype is the actual expression of those genes."
* Scientific context: "Researchers are studying the link between specific genotypes and the risk of developing certain diseases."
* Everyday use: "Knowing your genotype for certain genes can provide insights into your health and ancestry."
