Contoh meiosis

• Meiosis in protists : recent advances and persisting problems.

• The rest of the mutations were clearly generated during meiosis and occurred in tetrads with any progenitor alleles.

• We wanted to find out whether such treatment affects the ability of the egg to complete the meiosis and to transform nuclei of spermatozoa.

• Immature oocytes contained intact germinal vesicles; mature oocytes resumed meiosis and had undergone germinal vesicle breakdown.

• We conclude that this mechanism has probably already developed by the time the germ cells have become committed to meiosis.

• Our results here indicate that this factor or factors may have developed by the time the germ cells have become committed to meiosis.

• As growth is completed, transcription becomes silent, and sufficient molecules are stored in the oocytes for meiosis and full developmental competence.

• Effect of prematuration, meiosis activating sterol and enriched maturation medium on the nuclear maturation and competence to development of calf oocytes.

• In less well-spread preparations it was apparent that the triploids failed in meiosis.

• This allows for comparisons to be drawn between strains that are capable or incapable of undergoing meiosis, without the confounding effects of differences in ploidy.

• Note that after a renaming of the constitutive elements, the inclusion of the recombination step makes the whole process a canonical example of meiosis.

• Function and characteristics of repetitive calcium waves associated with meiosis.

• Resumption of meiosis: mechanism involved in meiotic progression and its relation with developmental competence.

• As an oocyte grows, its diameter increases and the competence to complete meiosis also is improved.

• It is not understood how oocytes acquire meiotic competence during their growth phase to become competent to resume and complete meiosis.
