The correct Answer is:
To solve the question regarding the incorrect statement about reciprocal crosses, we will analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding Reciprocal Cross**: A reciprocal cross involves two individuals with contrasting phenotypes. This type of cross is used to determine whether the inheritance of a trait is influenced by sex chromosomes or autosomes. 2. **Analyzing Option (a)**: - **Statement**: "To know whether the alleles are present on sex chromosomes or autosomes." - **Analysis**: This statement is true. Reciprocal crosses are indeed used to determine if alleles are located on sex chromosomes or autosomes. 3. **Analyzing Option (b)**: - **Statement**: "It is made to eliminate the effect of nuclear traits." - **Analysis**: This statement is incorrect. Reciprocal crosses do not aim to eliminate the effect of nuclear traits; rather, they help in understanding the inheritance patterns of traits. 4. **Analyzing Option (c)**: - **Statement**: "Two individuals with contrast genotypes are involved." - **Analysis**: This statement is true. Reciprocal crosses involve individuals with contrasting genotypes to observe the inheritance of traits. 5. **Analyzing Option (d)**: - **Statement**: "Results are not changed for autosomal traits." - **Analysis**: This statement is true. For autosomal traits, the results of reciprocal crosses remain the same regardless of which parent contributes the allele. 6. **Conclusion**: After analyzing all options, we find that option (b) is the incorrect statement regarding reciprocal crosses. ### Final Answer: The incorrect statement with respect to reciprocal cross is **(b) It is made to eliminate the effect of nuclear traits.** ---
