the smaller daughter nucleus of a fertilised dividing ovum.
A nonfunctional nucleus produced by meiosis, accompanied by very little cytoplasm. The meiosis which produces the mammalian egg produces in addition three polar bodies.
a small cytoplasmic exclusion body formed from the excess DNA formed during the egg meiotic cycle and following sperm fertilization. (More? Week 1 Notes)
a small cell containing little cytoplasm that is produced along with the oocyte and later discarded
a cell containing very little cytoplasm that is produced in the first or second meiotic division
a small section of an egg and contains the complementary set of chromosomes present in the oocyte
a small section of an egg that has been jettisoned with a copy of the chromosomes of that egg
A small cell generated during female meiosis, enabling cytoplasm to be partitioned into just one of the four meiotic products, the ovum. 204
A small haploid cell, produced during oogenesis in female animals, that does not develop into a functional ovum. A similar situation arises in the development of the egg cell of higher plants, in which only one fertile gamete is produced from meiosis.
The small abortive cells with a haploid chromosome complement, consisting of a tiny piece of cytoplasm and a nucleus, resulting from an unequal division of the primary oocyte.
The discarded genetic material resulting from femalegerm cell division. When an egg matures it discards half of its genetic materialso that the egg cell is ready to fuse with half the male genes inside a sperm.This discarded genetic material can be seen in the egg as a small round pieceof cytoplasm at the edge of the egg cell. The presence of a polar body tellsus whether an egg is mature or immature.
Two microscopic structures that are produced by the ripening egg and degenerate after fertilization. Examination of the polar bodies provides an indication of the egg’s chromosomal content.
Gr. polos - a pole; L. corpus - body]. A minute cell formed during the first and/or second meiotic divisions of oogenesis that contain a nucleus but very little cytoplasm and which eventually degenerate.
in animals, each meiotic division of the oocyte leads to the formation of one large cell (the egg) and a small polar body as the other cell.
The discarded genetic material resulting from female germ cell division. See Meiosis.
The Polar body is a cell structure found inside an ovum. Both animal and plant ova possess it.
