Viefleur [7K]

The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle

DedPeter [7]

The answer is pronuclei. A pronuclei is the state of the nucleus of either the sperm or the ovum after the sperm has entered the ovum but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane of the sperm pronuclei dissolves hence leaving no barrier for the two genetic materials to combine.
