The correct Answer is:
To solve the question of selecting the odd one out with respect to the chromosomal theory of inheritance, we will analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding the Chromosomal Theory of Inheritance**: - The chromosomal theory of inheritance states that chromosomes are the carriers of genetic information. It was proposed by Sutton and Boveri in the early 1900s. 2. **Analyzing Option 1**: - **Statement**: "It was proposed by Schutten and Voveri." - **Evaluation**: This statement is correct as the theory was indeed proposed by Sutton and Boveri. Therefore, this option is not the odd one out. 3. **Analyzing Option 2**: - **Statement**: "Behavior of chromosome is parallel to behavior of gene." - **Evaluation**: This statement is also correct because the behavior of chromosomes during cell division is linked to the behavior of genes, as genes are located on chromosomes. Hence, this option is not the odd one out. 4. **Analyzing Option 3**: - **Statement**: "Chromosomes and genes occur in pairs in diploid cells respectively." - **Evaluation**: This statement is misleading. While chromosomes do occur in pairs in diploid cells, the statement does not accurately reflect the chromosomal theory of inheritance, which focuses on the role of chromosomes as carriers of genes rather than the pairing of genes. Therefore, this option is the odd one out. 5. **Analyzing Option 4**: - **Statement**: "The paired condition of both chromosomes as well as Mendelian factor is restored during fertilization." - **Evaluation**: This statement is correct as it describes the restoration of paired chromosomes during fertilization, which is consistent with Mendelian genetics. Thus, this option is not the odd one out. ### Conclusion: After analyzing all the options, **Option 3** is the odd one out with respect to the chromosomal theory of inheritance.
