Phenotypes
B
Alleles
C
Codons
D
Chromatids
Verified step by step guidance1
Understand that a gene is a segment of DNA located at a specific position, or locus, on a chromosome.
Recognize that different versions or variants of the same gene found at the same locus are called alleles.
Recall that alleles can result in different traits or characteristics, which are observed as phenotypes.
Note that codons are sequences of three nucleotides in mRNA that specify amino acids, not different forms of a gene.
Remember that chromatids are duplicated strands of a chromosome, not variants of a gene.
