The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Reciprocal Crosses**: - A reciprocal cross involves two different crosses where the roles of the male and female parents are switched. For example, if we have a dominant trait represented by "R" and a recessive trait represented by "r", one cross could be: - Male: R (dominant) x Female: r (recessive) - The reciprocal cross would be: - Male: r (recessive) x Female: R (dominant) 2. **Mendel's Observations**: - Mendel performed these reciprocal crosses and observed that the results were identical regardless of which parent carried the dominant or recessive trait. This means that the offspring produced from both crosses had the same phenotypic ratios. 3. **Conclusion from Mendel's Findings**: - From his findings, Mendel concluded that the sex of the parent does not influence the inheritance of traits. This implies that the traits are inherited independently of the parent's sex. 4. **Analyzing the Options**: - **Option 1**: "There is no dominance of any trait." - This is incorrect because dominance can exist; Mendel's work showed that some traits are dominant over others. - **Option 2**: "Sex has no influence on the dominance of traits." - This is correct, as Mendel concluded that the results of the reciprocal crosses were identical, indicating that sex does not affect trait dominance. - **Option 3**: "There is independent assortment." - While independent assortment is a principle of inheritance, it is not specifically concluded from the reciprocal crosses. - **Option 4**: "Sex plays a role in deciding the dominance of a trait." - This is incorrect as Mendel's experiments showed no such influence. 5. **Final Conclusion**: - The correct conclusion from Mendel's experiments with reciprocal crosses is that sex has no influence on the dominance of traits.
