Select 5 correct answer(s) Question 5 options: A) In fruit flies, sex is determined by the ratio of the number of X chromosomes to sets of autosomes.. B) In mammals, sex is determined by a single gene on the X chromosome. C) Sister chromatids are held together by unreplicated centromeres. D) Crossovers, in combination with sister chromatid cohesion, physically connect homologs at metaphase of meiosis I. E) Homologous chromosomes have identical DNA sequences. F) In mammals, sex is determined by a single gene on the Y chromosome. G) At mitosis, microtubules attach to kinetochores located at telomeres to segregate sister chromatids to opposite poles. H) Chromosomes that fail to have at least one crossover have an increased risk of meiosis I…
Can you guys complete this assignment? The instructions say “You will track and draw chromosome of a diploid organism through all the stages of mitosis. Make sure to replicate the chromosomes when appropriate and separate the chromosome pairs or the chromatids at the correct stages. Also, make sure you draw the alleles for genes A and B on the chromatids in every stage. Fill in the genotypes where indicated on the empty boxes.”
Need help with three question. Multiple choise. 1.) How is the outcome of meiosis different from the outcome of mitosis? a.) The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. b.) The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. c.) The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. d.) The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells. 2.) What would be the effect on the number of chromosomes in gametes due to non-disjunction? a.) The chromosome number of the gametes remains the same as the parent…

Write True or False 1. In prophase of mitosis the chromosomes condense in y sharp structure that can be easily seen under microscope 2. In interphase stage of mitosis a membrane forms around each set of chromosomes to create two new nuclei 3. In interphase l of meiosis, the paired chromosomes line up 4. In prophase ll of meiosis, it is visibly obvious that replication has not occurred 5. In telophase l of meiosis, the cell pinches and divides 6. Homologous chromosomes contain the unmatched alleles donated from mother and father 7. In anaphase of mitosis, the sister chromatids are pulled apart by the mitotic spindle which pulls one chromatid to one pole and the chromatid opposite pole 8.At the end of the prophase in mitosis, the membrane around the nucleus in the cell dissolves away releasing the chromosomes. 9.During interphase in mitosis, microtubules extend from centrosomes. 10.If not corrected in time, mistakes made during mitosis can result changes in DNA but will not lead to…
