(1) In charophytes, the first cell division of the zygote is meiosis, and their plant body is gametophytic.(2) Early embryonic development in many plants is characterized by asymmetric cell division of the zygote , which specifies apical and basal regions.(3) The fusion of egg and sperm restores the diploid chromosome number in the zygote .(4) Otherwise, abnormal mitosis occurs, which typically results in zygotic death.(5) A post zygotic mutation restricted to somatic cells has been assumed to be responsible for most cases.(6) A brief exposure to chloroform vapors kills vegetative cells but not zygotes .(7) Several gametic and zygotic reproductive barriers were found in a cross between Japonica and Indica rice varieties.(8) It is the sperm basal body that serves as a centriole in the zygotic microtubule organizing center.(9) Those 10 frozen little 16 or 32 cell zygotes will never be used for anything else.(10) Most of the regions identified by these deficiencies do not contain previously identified zygotic cell death genes.(11) Conjugation frequencies were calculated by dividing the number of zygotes (one zygote counted as two cells) by the total number of cells present.
