The correct Answer is:
To solve the question "When a certain character is inherited only through the female parent, it probably represents," we need to analyze the options provided and understand the concepts of inheritance. ### Step-by-Step Solution: 1. **Understanding Inheritance Types**: - We need to consider the different types of inheritance mentioned in the options: multiple plastic inheritance, cytoplasmic inheritance, incomplete dominance, and Mendelian nuclear inheritance. 2. **Analyzing Cytoplasmic Inheritance**: - Cytoplasmic inheritance refers to the transmission of genetic material that occurs outside the nucleus, specifically through organelles like mitochondria and chloroplasts. In humans, mitochondrial DNA is inherited exclusively from the mother because the mitochondria in the sperm are usually destroyed after fertilization. 3. **Examining the Role of Mitochondria**: - Since mitochondria contain their own DNA and are passed down from the mother, any traits associated with mitochondrial DNA will be inherited only through the female parent. This is a key point in understanding why certain characters can be exclusively maternal. 4. **Evaluating Other Options**: - **Multiple Plastic Inheritance**: This term does not specifically relate to inheritance through the female parent. - **Incomplete Dominance**: This refers to a situation where neither allele is completely dominant, resulting in a blend of traits, but does not pertain to maternal inheritance. - **Mendelian Nuclear Inheritance**: This involves the inheritance of traits through nuclear DNA, which can be inherited from both parents, not exclusively from the female. 5. **Conclusion**: - Based on the analysis, the character that is inherited only through the female parent most likely represents **cytoplasmic inheritance**. ### Final Answer: The correct answer is **cytoplasmic inheritance**.

According to hybridisation theory, the % s-character in sp, sp^(2) and sp^(3) hybrid orbitals is 50, 33.3 and 25 respectively, but this is not true for all the species. When theta is the bond angle between equivalent hybrid orbitals then % s and p-character in hybrid orbitals (when only s and p-orbitals are involved in hybridisation) can be calculated by the following formula : costheta=(S)/(S-1)=(P-1)/(P) Q. Two elements X and Y combined together to form a covalent compound. If % p-character is found to be 80% in a orbital then the hybridised state of central atom X for the orbital is :
