- Kuliev and Verlinsky (2004) state that there was a relatively high number of separation errors at meiosis I. In these cases the centromere underwent a premature division, occurring at meiosis I rather than meiosis II. Regarding chromosome 21, what would you expect to be the chromosome 21 complement in the secondary oocyte in which you saw a single chromatid (monad) for chromosome 21 in the first polar body? If this secondary oocyte was involved in fertilization, what would be the expected consequences?arrow_forwardSomatic cells in organisms of a certain diploid plant species normally have 14 chromosomes. The chromosomes in the gametes are numbered from 1 through 7. Rarely, zygotes are formed that contain more or fewer than 14 chromosomes.

Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell?

- Based on the attached image, identify the stage at which each cell is in and draw an animal cell with a diploid chromosome number of 6. Indicate maternally- & paternally-derived chromosomes as red and blue, respectively, in your diagram. You do not need to indicate any crossing over. Be sure to include any of the indicated labels. On your diagram, indicate the # of chromosomes and # of homologous pairs in the stage of meiosis I (attached image), whether they are duplicated or not, and whether the cell has an n, 2n, or 4n complement of chromosomes. Also label homologous chromosomes, nonsister chromatids, and kinetochore microtubules.arrow_forwardA diploid organism produces four gametes from one parent cell through the process of meiosis. Two gametes are found to have 7 chromosomes and two gametes are found to have 5 chromosomes. A) Is this the expected number of chromosomes that would be found in each gamete following a normal cycle of meiosis? If yes, explain why. If no, explain why not and describe how the gamete situation described above occurred. B) Determine the number of homologous chromosome pairs that the original parent cell contained, before meiosis began. Explain how you determined this value.arrow_forwardConsider and individual with 3 pairs of homologous chromosomes labeled as: A/a B/b D/d(where the slash line separates one chromosome from its homologues). How many differentmeiotic products (sperm or egg) can this individual produce? What are these?arrow_forward
