pronucleus
(Science: molecular biology) haploid nucleus resulting from meiosis.
In animals the female pronucleus is the nucleus of the ovum before fusion with the male pronucleus. The male pronucleus is the sperm nucleus after it has entered the ovum at fertilization but before fusion with the female pronucleus.
In plants the pronuclei are the two male nuclei found in the pollen tube.
