Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Formation of chiasma 2. Each chromatid is considered as full-fledged chromosome. 3. Chromosomes begin to pair off. 4. Spindle microtubules start to attach to the centromere. 5. Tetrads are aligned at the middle of the cell. 6. The sister chromatids separate. 7. Produce 2 haploid daughter cells. 8. The chromosomes line up at the middle of the cell. 9. The sister chromatids move together to the opposite poles. 10. The chromatids reach the poles. 11. The chromosomes in each daughter cell are still duplicated.12. Spindle microtubules attach in the centromere of each haploid daughter cell. 13.

USING TWO DIFFERENT COLORS TO SIGNIFY THE MATERNAL AND PATERNAL CHROMOSOMES, DRAW THE RESPECTIVE CELLS IN EACH LABELED PHASE OF MITOSIS AND MEIOSIS. THE CHROMOSOME NUMBER WILL BE "4" AND SHOULD BE REPRESENTED AS TWO HOMOLOGOUS PAIRS. MAKE SURE YOU USE TWO DIFFERENT SIZES FOR EACH OF THE PAIRS. BELOW EACH PHASE, BRIEFLY DESCRIBE WHAT HAPPENS.

6) The plant Haplepoppus gracilis is diploid (2n = 4). Inside each cell (represented here by the oval) there are four total chromosomes: one long pair (represented by "A" and "a") and one short pair (represented by "B" and “b"). The following diagrams represent possible anaphases of this cell during meiosis or mitosis. The lines represent chromosomes/chromatids being pulled to either the north or south pole of the cell, and the vertex of each "V" represent the centromere which would be attached to kinetochore microtubules. For representative cells 1– 12, say if the diagram represents a cell in anaphase I of meiosis I, anaphase II of meiosis II, anaphase of mitosis, or shows an impossible situation. If the situation is impossible, explain why. い。 VA Vb VA VB VV. V b Va VB VAVA Vo VB ^^ ^ が VaVA Vo VB くs
3) For each cell below, identify the meiosis phase (meiosis I or II) and stage of meiosis it is in (or if it is in interphase).
Consider a diploid cell that contains 7 pairs of chromosomes. Each pair includes a maternal and a paternal member (for example: AP pair) or AP B ^ n * B ^ p (two pairs). How many different combinations of chromatids are possible during the early phases of anaphase in meiosis II?
Fill in the cells below showing the process of meiosis of the male's sex chromosomes with non- disjunction occurring during meiosis I. DO NOT show crossing over. Prior to meiosis 44 +XY What are the possible abnormal gametes the male can produce with non-disjunction occuring in Meiosis I? Identify the possible sexual aneuploidy syndrome if these abnormal sperm cells are fertilized by a normal egg cell. Could this man father a Tuner syndrome (XO) child? Could this man father a Klinefelter's syndrome child (XXY)?
Identify the stages of meiosis described by the following meiotic events/conditions/terms. Write prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, or telophase II. In case the events are found in both stages, write the stages both. 1. Separation of homologous chromosome 2. Four haploid daughter cells are formed.

Picture name - Tradescantia spathacea meiotic cell. HPO (400x)Shown below are photomicrographs of Rhoeo tradescantia cells undergoing meiosis. Answer the following question for each of the photomicrographs: Identify the cytogenetic abnormality observed (ex. ring, chain, laggard, bridge). Identify the meiotic stage in which these aberrations are observed (as shown in the photomicrograph). Explain how these aberrations are formed and relate to the possible causal mutation(s). Will this result to sterile and/or fertile gametes? Explain.
