sustantivo

Biology
Each of the small cells which bud off from an oocyte at the two meiotic divisions and do not develop into ova.
Oraciones de ejemplo
  • In most multicellular organisms, each of the two meiotic divisions in females results in an oocyte and a polar body, each of which has a distinct morphology and developmental fate.
  • At this time, the primary oocyte's first meiotic division occurs, resulting in the formation of the first polar body and the secondary oocyte.
  • The implication of this suggestion is a chromosome segregation effect in which meiotic nondisjunction would more likely result in the retention of an additional chromosome in the oocyte than in the polar body.
