Mendel’s Law of independent assortment holds good for genes situated on the:
a. non-homologous chromosomes
b. homologous chromosomes
c. extranuclear genetic element
d. same chromosome
The answer is the option (a) Non-homologous chromosomes
Explanation: All the other three options (b), (c) and (d) do not exhibit independent assortment. For the genus on the homologous chromosome, Mendel's independent assortment rule works well. Humans and other diploid organisms have two copies of their genome in each cell. By giving each chromosome two copies, or homologous chromosomes, it contributes to a population's increased stability and diversity. Hence, (a) is the right answer.
