B

C
Chromatids
D
Phenotypes
Verified step by step guidance1
Understand that genes are segments of DNA located at specific positions (loci) on chromosomes.
Recognize that homologous chromosomes carry the same genes at the same loci but can have different versions of these genes.
Learn that these different versions of a gene are called alleles.
Note that alleles can result in variations in the trait controlled by the gene, such as different eye colors.
Distinguish alleles from other terms: codons are triplets of nucleotides coding for amino acids, chromatids are duplicated chromosome arms, and phenotypes are observable traits.
