Understand that a gene is a segment of DNA that codes for a specific trait or protein.
Recognize that genes can have different forms or variations, which lead to different expressions of a trait.
Learn that each of these different forms of a gene is called an allele.
Note that a codon is a sequence of three nucleotides in mRNA that codes for an amino acid, not a gene variant.
Remember that a chromosome is a structure made of DNA that contains many genes, and genotype refers to the genetic makeup of an organism, not a single gene version.
