Meiosis Flashcards
(23 cards)
What process converts diploid nuclei to haploid nuclei?
Meiosis.
Where does meiosis occur to produce gametes?
Sex organs.
What is the result of fertilization?
Zygote.
What is the first phase of Meiosis I?
Interphase I.
How many phases are in Meiosis II?
Four.
How many phases are in Meiosis I?
Five.
What happens during Interphase I?
DNA Replication.
What is the process called where homologous chromosomes pair up in Meiosis I?
Synapsis.
What is formed when homologous chromosomes come together?
Tetrad.
What is the exchange of genetic material between non-sister chromatids called?
Crossing over.
What are the sites where non-sister chromatids join during crossing over called?
Chiasmata.
What is the second phase of Meiosis I?
Prophase I.
In which phase do homologous pairs align at the cell equator?
Metaphase I.
What happens during Anaphase I?
Duplicated chromosomes move to opposite poles.
What is the final phase of Meiosis I?
Telophase I.
What forms around chromosomes during Telophase I?
Nuclear envelope.
What happens to the number of chromosomes in each nucleus after Telophase I?
Haploid.
What is the first phase of Meiosis II?
Prophase II.
In which phase do individual duplicated chromosomes align on the equator?
Metaphase II.
What happens during Anaphase II?
Duplicated chromosomes split and move to opposite poles.
What is the final phase of Meiosis II?
Telophase II.
How many daughter haploid cells are formed at the end of Meiosis II?
Four.
What forms around chromatin during Telophase II?
Nuclear envelope.
