Stack #127503

QuestionAnswer
metaphase I pairs of homologous chromosomes line up at the equator
prophase II a new spindle forms around the chromosomes
telophase I chromosomes gather at the poles, the cytoplasm divides
metaphase II chromosomes line up at the equator
telophase II a nuclear envelope forms around each set of chromosomes, the spindle breaks down, and the cytoplasm divides, resulting in four haploid cells
anaphase II centromeres divide, enabling the chromatids, now called chromosomes, to move to opposite poles of the cell
prophase I the nuclear envelope breaks down; genetic material is exchanged through crossing-over
anaphase I chromatids remain attached at their centromeres as the spindle fibers move the homologous chromosomes to opposite poles of the cell
ogenesis the production, growth and maturation of an egg or ovum
tetrad the four chromatids in a pair of homologos chromosomes that come together as a result of synapsis during meiosis
polar bodies a short-lived product of the formation of gametes by meiosis
during synapsis, the chromosomes line up next to their homologues
during cross-over, portions of chromatids seperate from each other and move to opposite poles of the cell
in which phase of meiosis do tetrads form prophase I
meiosis II seperates chomatids into opposite poles of the cell
in oogenesis, a diploid reproductive cell divides meiotically to produce one diploid gamete

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
