Answer:
Gene
Explanation:
A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism
Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
