**Cytoplasmic Inheritance and Reciprocal Cross**

Inheritance refers to the passing of traits from parents to offspring. It can occur through various mechanisms, such as nuclear inheritance, cytoplasmic inheritance, or a combination of both. However, in the case of reciprocal cross, the results are affected by cytoplasmic inheritance.

**Cytoplasmic Inheritance:**
Cytoplasmic inheritance involves the transmission of genetic material through cytoplasmic organelles, such as mitochondria or chloroplasts, rather than the nuclear genome. These organelles have their own DNA, which is separate from the nuclear DNA. As a result, specific traits controlled by the cytoplasmic DNA can be inherited independently of the nuclear genome.

**Reciprocal Cross:**
A reciprocal cross is a breeding experiment in which the sexes of the parents are reversed. For example, if the original cross is between a male parent with a certain trait and a female parent without that trait, a reciprocal cross would involve mating a male parent without the trait with a female parent possessing the trait. This allows researchers to determine whether the observed trait is influenced by the sex of the parent or if it is solely dependent on the genetics of the offspring.

**Effect of Cytoplasmic Inheritance on Reciprocal Cross:**
In the case of cytoplasmic inheritance, the results of a reciprocal cross can be influenced by the cytoplasmic DNA inherited from the male and female parents. This is because cytoplasmic DNA is passed down exclusively through the female parent.

If a trait is influenced by cytoplasmic inheritance, the offspring resulting from reciprocal crosses will exhibit different phenotypes depending on the cytoplasmic DNA inherited from the male and female parents. This is because the cytoplasmic DNA can contain specific genes or mutations that affect the expression of certain traits. Therefore, the results of a reciprocal cross can reveal the contribution of cytoplasmic inheritance to the observed trait.

**Conclusion:**
In summary, the results of a reciprocal cross can be affected by cytoplasmic inheritance. This type of inheritance involves the transmission of genetic material through cytoplasmic organelles and can influence the expression of specific traits. By performing reciprocal crosses, researchers can determine whether a trait is influenced by cytoplasmic inheritance or solely dependent on the nuclear genome. Therefore, the correct answer is option B: Cytoplasmic inheritance.
