I need help with a biology question, please see the image below, thanks Answer the following from the image with letters A,B,C, or D For an organism with a diploid number of 6, how are the chromosomes arranged during metaphase I of meiosis? Which sketch shows the arrangement of chromosomes that you would expect to see in metaphase of mitosis for a cell with a diploid chromosome number of 6? For an organism with a diploid number of 6, how are the chromosomes arranged during metaphase 2 of meiosis?

Which of the following is true in comparing a cell's genetic information at the beginning of Meiosis II towards the end of Meiosis II? O It has twice the DNA of the cell that began meiosis. O It has one-fourth the DNA and one-half the chromosomes as the cell that began meiosis II. O It has the same amount of DNA at the beginning and end of Meiosis II It has half the amount of DNA as the cell that began meiosis.
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

Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.

Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. (There needs to be a model drawing) What would a 2n=10 cell look like during prophase I? What would that cell look like during metaphase I? At the end of meiosis I? During metaphase II? At the end of meiosis II?
The mosquito, Aedes aegypti, has 3 bivalents (homologous pairs) formed at Meiosis I. How many chromosomes and chromatin strands are present in each of the following stages:
