androgenesis

 [an″dro-jen´ĕ-sis]
a phenomenon in which an ovum is fertilized by a haploid sperm, which then duplicates its own chromosomes after meiosis; the chromosomes of the ovum are either absent or inactivated. This is often associated with complete molar pregnancies.

an·dro·gen·e·sis

(an'drō-jen'ĕ-sis),
Development in the presence of paternal chromosomes only.
[andro- + G. genesis, production]

androgenesis

/an·dro·gen·e·sis/ (an″dro-jen´ĕ-sis) development of a zygote that contains only paternal chromosomes, as after fertilization of an oocyte whose chromosomes are absent or inactivated.
