Answer:
The correct option is <em>B. Crossing- over </em>

In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.
The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.
Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.

Explanation:
Cell Cycle Regulators. The cell cycle controls replication and apoptosis, prevents uncontrolled cell division (tumor formation), and may involve detection and repair of damage to DNA. ... Sigma offers a host of cell cycle regulators such as antimitotics, mitotic inhibitors, and cytokinesis inhibitors.
Genetic variation is advantageous because it enables some individuals and, therefore, a population, to survive despite a changing environment.
