Cell cycle is regulated by master regulators (cyclin and CDKs). In vertebrates, G1 CDK activity rises during G1 and is stimulated by the presence of growth factors. When signaling from growth factors is sustained, the resulting cyclin D–CDK4/6 complexes begin phosphorylating Rb, releasing some E2F, which stimulates transcription of the genes encoding cyclin E, CDK2, and E2F itself. In a particular cell type there is a mutation in Rb such that it cannot be phosphorylated. What will be the correct expression pattern of cyclin E in these cells after mitotic stimulation?

A. Non-Mendelian inheritance is defined by the failure of the offspring of a mating to display Mendelian segregation for parental characters. 

B. For Non-Mendelian inheritance, presence of genes that are outside the nucleus and are not distributed to gametes or to daughter cells by segregation on the meiotic or mitotic spindles.
