A diploid cell has 15 picograms of DNA in G₁ phase. If this cell is a germ line cell that undergoes meiosis, how much DNA will each daughter cell contain at the end of
meiosis I? How much DNA will each daughter cell contain at the end of meiosis II?
MI = 30 pg: MII = 15 pg
O MI = 15 pg; MII = 15 pg
MI = 7.5 pg; MII = 15 pg
O MI = 15 pg: MII = 7.5 pg
In experiment of Following chromosomal DNA movement through meiosis, what is the trial 1 and trial 2 meiotic division beads diagram for prophase l, metaphase l, anapahse l, telophase l, prophase ll, metaphase ll, anaphase ll, telophase ll, and cytokinesis?
In a turtle species, a diploid cell in the G1 phase of the cell cycle contains 22 picograms of DNA (picogram is a measure of the total mass of the DNA present). How much DNA is present in a cell of the same species at prophase II of meiosis (prophase of the second meiotic division)?

- During metaphase I of meiosis, tetrads align along the metaphase plate independently of each other. Therefore, there is a random “shuffle” of maternal and paternal chromosomes in the resulting gametes.The following diagram demonstrates how this works in a diploid cell with four chromosomes (2n=4) . Because there are two pairs of chromosomes and each pair can align in one of two ways during metaphase I, the number of possible variations in the gametes produced is 22 or 4.For an organism that is , there are three pairs of chromosomes, so the number of possible variations in the gametes produced due to independent assortment in metaphase I is 23 or 8. In an organism with a haploid number of 7, how many possible combinations of maternal and paternal chromosomes can occur in its gametes? a. 72=49 b. 27=128 c.17=1 d. 214=16 384arrow_forwardDuring metaphase I of meiosis, tetrads align along the metaphase plate independently of each other.
