Verified step by step guidance1
Understand that a gene is a segment of DNA located at a specific position (locus) on a chromosome.
Recognize that different versions or variants of the same gene that occupy the same locus on homologous chromosomes are called 'alleles'.
Recall that 'codons' are sequences of three nucleotides in mRNA that specify amino acids, not different forms of a gene.
Note that 'homologous chromosomes' are pairs of chromosomes, one from each parent, that carry the same genes but not necessarily the same alleles.
Understand that 'phenotypes' refer to the observable traits or characteristics resulting from the interaction of genotype and environment, not the gene variants themselves.
