i) How many chromosomes and chromatids were present in cell A during the G1 phase? Please clearly specify chromosomes and chromatids in your answer. ii) For cell A, list all the gametes that will be produced from this cell. Give the alleles of each gamete contained within a set of brackets. You may ignore independent assortment. iii) For cell B, list all the gametes that will be produced from this cell given crossing over. Give the alleles of each gamete contained within a set of brackets. You may assume that no crossing over would take place.

Expert Solution
Step 1

To divide, a cell must accomplish many things: expand, reproduce its genetic material (DNA), and essentially split into two daughter cells. The cell cycle is a structured and consistent set of stages in which cells accomplish their activities. Since the two daughter cells can continue the process from the beginning to the end, the cell cycle is a cycle rather than a linear pathway.
