In the fundamentals of genetics, variations of a gene are called:
A
Codons
B
Centromeres
C
Chromatids
D
Alleles
Verified step by step guidance1
Understand the question is asking for the term that describes variations of a gene.
Recall that a gene is a segment of DNA that codes for a specific trait, but this gene can have different forms or versions.
Recognize that these different forms or versions of the same gene are called alleles.
Review the other options: Codons are sequences of three nucleotides that code for amino acids; centromeres are regions of chromosomes; chromatids are duplicated chromosome arms.
Conclude that the correct term for variations of a gene is alleles.
