D
Allele
Verified step by step guidance1
Understand that genes are segments of DNA located at specific positions called loci on chromosomes.
Recognize that homologous chromosomes are pairs of chromosomes, one inherited from each parent, that have the same genes at the same loci.
Learn that different versions of the same gene at a particular locus are called alleles.
Note that alleles can vary in their DNA sequence, leading to different traits or phenotypes.
Distinguish alleles from other terms: a codon is a sequence of three nucleotides coding for an amino acid, a phenotype is the observable trait, and a chromatid is one half of a duplicated chromosome.
