Law of independent assortment can be explained with the help of

Options

A. dihybrid cross
B. test cross
C. back cross
D. monohybrid cross

Explanation

**Step-by-Step Solution:**

1. **Understanding the Law of Independent Assortment**:
- The Law of Independent Assortment states that alleles of two or more genes assort independently of one another during gamete formation. This means that the allele a gamete receives for one gene does not influence the allele received for another gene.

2. **Identifying the Types of Crosses**:
- To explain the Law of Independent Assortment, we need to consider the types of genetic crosses: dihybrid cross, test cross, back cross, and monohybrid cross.

3. **Dihybrid Cross**:
- A dihybrid cross involves two genes, each with two alleles. For example, in pea plants, we can consider seed shape (round vs. wrinkled) and seed color (yellow vs. green). The combinations of these traits can be represented as RRYY (round yellow), RrYy (round yellow), rrYY (wrinkled yellow), and so on.

4. **Demonstrating Independent Assortment**:
- In a dihybrid cross, the segregation of alleles for one gene occurs independently of the segregation of alleles for another gene. This can be visually represented using a Punnett square, which shows the possible combinations of gametes from the parents.

5. **Conclusion**:
- Since the Law of Independent Assortment specifically involves two or more genes, the best way to explain it is through a dihybrid cross. Other options like test cross, back cross, and monohybrid cross involve either one gene or specific combinations that do not demonstrate independent assortment.

6. **Final Answer**:
- Therefore, the Law of Independent Assortment can be explained with the help of a **dihybrid cross**.
