The number of nuclei present in a zygote is

A zygote marks the very beginning of a new organism’s life. It forms when a sperm cell successfully fertilizes an egg cell. This miraculous union combines genetic material from both parents, resulting in the creation of a unique and complete set of chromosomes, often referred to as a diploid cell.

At its inception, the zygote consists of a sole nucleus. This nucleus embodies the merged genetic blueprint from the sperm and egg, encompassing the full complement of chromosomes essential for the development and growth of the new organism.

This single nucleus within the zygote holds the genetic instructions necessary for the subsequent division and specialization of cells, laying the groundwork for the complex and intricate process of embryonic development. From this foundational moment, the zygote begins its remarkable journey, progressively dividing and differentiating to form the diverse array of cells and tissues needed for the growth and eventual maturation of the organism.
