- Figure 13.6 Which of the following statements about nondisjunction is true? Nondisjunction only results in gametes with n+1 or n-1 chromosomes. Nondisjunction occurring during meiosis II results in 50 percent normal gametes. Nondisjunction during meiosis I results in 50 percent normal gametes. Nondisjunction always results in four different kinds of gametes.We are following the progress of human chromosome 1 during meiosis. At the end of prophase I, how many chromosomes, chromatids, and centromeres are present to ensure that chromosome 1 faithfully traverses meiosis?Which statement best describes the genetic content of the two daughter cells in prophase II of meiosis? haploid with one copy of each gene haploid with two copies of each gene diploid with two copies of each gene diploid with four copies of each gene

- Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis. Make sure you label the alleles for genes on the chromosomes the whole way through - every chromatid should have labeled alleles. For meiosis, both crossing over and independent assortment can occur. For the purpose of this exercise, assume that there is a single crossover event on the long chromosome between the A and D genes. Only show crossing over after its fully occured. There are no crossover events on the short chromosome. Regarding independent assortment, there are two possible outcomes in meiosis if there are two homologous pairs of chromsomes. Include both independent assortment possibilities - one on the left side and one on the right. Fill in the possible gamete genotypes for each outcome. If you do this correctly you should end up with 8 different types of gametes. Image attached for genotypes and alleles. Give me a full explaination of each of…Assume that during meiosis I, none of the C chromosomes disjoin at metaphase, but they separate into dyads (instead of monads) during meiosis II.

- 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.
