Alleles of a gene are variations that exist for a particular trait, and they are found on:
Correct Answer
B. Homologous chromosomes
Explanation
Homologous chromosomes are pairs of chromosomes, one inherited from each parent, that contain the same genes at the same locations. Each chromosome in the pair can have different alleles for those genes.
Key Points
- Alleles are different forms of a gene.
- They are located at the same position on homologous chromosomes.
- Each parent contributes one chromosome to the pair, allowing for genetic variation.
