According to Mendel’s laws of dominance, when a plant with dominant trait is crossed with plant with recessive trait, it results into dominant phenotype in F1 offspring. In the given question, a plant with pointed leaves (P) are dominant and plant with round leaves (p) is recessive. On crossing a pointed leaves (PP) with a plant with round leaves (pp) a heterozygous (Pp) pant with pointed leaves will be produced.

Each axon is covered by multiple myelin sheaths and the gap between myelin sheath are known as Nodes of Ranvier.
In CNS myelin sheath is composed of glial cell called as oligodendrocytes and in PNS the myelin sheath is composed of Sachwann cells (glial cells).
