Question

How does an allelic gene interaction differ from a non-allelic gene interaction?
Options
A Allelic interactions involve alleles at the same locus, whereas non-allelic interactions involve genes at different loci (e.g., epistasis)
Correct Answer
B Allelic interactions only occur on mitochondrial DNA, while non-allelic occur in the nucleus
C Allelic interactions alter chromosomal chromosome number, while non-allelic interactions do not
D Allelic interactions describe crossing over between non-homologous chromatids
Correct Answer

Option A is the correct answer.

Detailed Explanation

Allelic interactions occur between alleles residing at the exact same genetic locus (e.g., dominance, codominance), whereas non-allelic interactions occur between distinct loci (e.g., epistasis).
