Source of mendelian recombination is

Options

A. Linkage
B. Independent assortment
C. Mutations
D. Dominat traits

Answer

**Step-by-Step Solution:**

1. **Understanding Mendelian Recombination**: Mendelian recombination refers to the formation of new combinations of alleles in the offspring, which results in genetic variation. This process is crucial for evolution and diversity in populations.

2. **Analyzing the Options**:
- **Linkage**: This refers to genes that are located close to each other on the same chromosome and tend to be inherited together. Mendel's experiments were based on traits that did not show linkage, making this option incorrect.

- **Independent Assortment**: According to Mendel's second law, the alleles of different genes assort independently of one another during gamete formation. This means that the inheritance of one trait does not affect the inheritance of another, allowing for new combinations of traits in the offspring. This is a key source of Mendelian recombination.

- **Mutations**: While mutations can lead to new genetic variations, they were not a factor in Mendel's original experiments, which focused on traits that were already established. Therefore, this option is also incorrect in the context of Mendelian recombination.

- **Dominant Traits**: Dominant traits do not contribute to new combinations; they simply mask the effects of recessive traits. This option does not lead to recombination, making it incorrect.

3. **Conclusion**: The correct source of Mendelian recombination is **independent assortment**.

**Final Answer**: The source of Mendelian recombination is independent assortment.
