In the context of Mendelian genetics, what term describes different forms of a gene at the same locus?
A
Alleles
B
Chromatids
C
Centromeres
D
Gametes
Verified step by step guidance1
Understand that in Mendelian genetics, a gene is located at a specific position on a chromosome called a locus.
Recognize that different versions or variations of the same gene found at the same locus are called different forms of that gene.
Recall the terminology used in genetics: the term for these different forms of a gene is 'alleles'.
Differentiate alleles from other terms: chromatids are duplicated chromosome strands, centromeres are chromosome regions where chromatids attach, and gametes are reproductive cells.
Conclude that the correct term describing different forms of a gene at the same locus is 'alleles'.
