variation

mutations

Explanation:

Each term is defined with core genetic/biological context, and examples are selected to illustrate key real-world or molecular instances.

Answer:

Term	Definition	Examples
Heterozygous	Having two different alleles for a gene	Tt (tall pea plant), Ss (carrier for sickle cell)
Genetics	Study of heredity and gene variation	Gregor Mendel's pea plant experiments, CRISPR gene editing
Inheritance	Passing of traits from parent to offspring	Eye color inheritance, cystic fibrosis transmission
Protein	Molecule made of amino acids, encoded by genes	Hemoglobin (carries oxygen), Insulin (regulates blood sugar)
Nucleotides	Building blocks of DNA/RNA	Adenine (A), Thymine (T), Cytosine (C), Guanine (G), Uracil (U)
Variation	Differences in traits between organisms	Human height range, peppered moth color morphs
Mutations	Permanent changes in DNA sequence	Sickle cell anemia mutation, BRCA1 breast cancer mutation
