Question

1 Draw out the phases of meiosis for a (2n=4) germ line cell: Use red and blue to indicate ate the two sets of chromosomes aleat There should be two throughout the various phases-red will represent the maternal set and blue will represent the paterials alternate scenarios for how the homologous pairs could alian during metaphase. When applicable, bus pairs could alian during metaphase. When applicable, all of the phase drawings (pre- prase o resulting daughter cells) should include the nuclear envelope, chromosome locations, centrosomes, como Taments (spindle fibers), and the metaphase plate. (These structures do not need to be labeled 2. In one of the scenarios above: Label and point to crossing over occurring 3. In one of the scenarios above: Label and point to independent assortment occurring 4. The two consecutive rounds of meiosis results in (#) daughter cells that are genetically 5. In mitosis, duplicated chromosomes are aligned and then separated. In meiosis, pairs of chromosomes are aligned and then separated. 6. During meiosis, the total number of chromosomes and the number of chromosome sets is cut in half in preparation for sexual reproduction. The (2n=4) germ line cell started out with a total of _ _chromosomes and sets of chromosomes. The daughter cells that were produced as a result of meiosis I have a total of chromosomes and sets of chromosomes. These daughter cells are (diploid/haploid). 7. Are the chromosomes in the daughter cells for both scenarios in their duplicated or unduplicated form? Explain why these daughter cells would have to undergo meiosis Il prior to fertilization.

please solve this asap thank you so much
